Recycle Silicone Oil


Dialkylpolysiloxanes also known as silicone, are man-made polymers that include any inert, synthetic compound made up of repeating units of siloxane, which is a chain of alternating silicon atoms and oxygen atoms, frequently combined with carbon or hydrogen or both.

They are occurring in many physical forms as low and high viscosity fluid, gel, gums, rubber, resins etc having variety of applications in industry as well as in our day to day life.

Various functionalities to the basic backbone chain of silicones impart different physical and chemical properties, as a result mostly adopted polymer in improving the quality of life by mankind.

Silicone, thus having various added advantage as far as applicability concern, poses high concerns due to its poor degradation rate naturally. This increases the risk of accumulation of waste silicone polymer all over the globe.

An approach to address the recycle of this waste silicone polymer with an environmental benign, non- hazardous, economical, safe way need to be reviewed.

Recycling of silicone polymer implies reuse of the waste polymer as polymer; broadly categories as

  1. recycling of industrial scrap and
  2. Post-consumer recycling

The former primarily involves recovering and reusing waste polymer resulting from processing operations. This has long been practiced by many industrial groups. It is simpler than the latter.

In post consumer recycling of polymers, they are particularly of mixed kind and they are collected and segregated by experienced people. The practice is motivated by economics.

Therefore, efficient recycling should give new opportunities for reintegration of discarded materials into the economic cycle, increase the added value of products out of recycled materials, create a sustainable solution to the polymer waste problem, and decrease dependence  of  businesses  on  oil-based  raw  materials  and  energy.  The most common recycling methods are mechanical recycling, chemical recycling, and combustion.

Supreme Silicones, through its continuous R&D activities, achieved mastery over economic recycling of silicone polymers. Comminuted Silicones polymers are fed to reactor for chemical degradation in presence of catalyst to depolymerise the siloxane backbone. The cleavage of bonds take place as energy required for bond dissociation is supplied in the form of heat. The catalyst alters the rate of reaction and the process results in formation of silicon monomeric materials. Reactions can be fine tuned to get the desired low molecular weight polymers. Various functional silicone polymers and its copolymers can be synthesised using this technique.

Advantages :

Recycling minimizes pollution

All forms of pollution in the modern world emanate from industrial waste. Recycling of the industrial wastes such as plastics, cans, and chemicals go a long way towards considerably cutting back on levels of pollution because these waste products are reused rather than just being thrown away recklessly.

Protects the environment

The great benefit of recycling waste material is that it plays a big part in protecting Mother Nature in the most balanced way. While many trees are felled every day, recycled paper manufactured from specific trees is continually utilized to reduce deforestation. This classical example demonstrates that other natural resources can be recycled and made useful this way to conserve the environment.

Recycling minimizes global warming

It is perfectly true that recycling minimizes global warming and its grave impacts. During waste disposal, huge amounts of waste are combusted that lead to emission of vast greenhouse gases such as carbon dioxide, sulfur, and nitrogen, which contribute to climate change and global warming.

Recycling process involves minimal combustion and waste is transformed into reusable materials with zero or minimal harmful impact on the environment. The whole process of processing and manufacturing products from waste materials emits few greenhouse gases because the very waste recycling industries burn little fossil fuels.

Conserves natural resources

If the process of recycling used and old materials was not there, it means new products will be manufactured by extraction of fresh raw materials underneath the earth through the process of mining and extraction. Recycling is a surefire way of conserving existing raw materials and protecting them for future use. Taking steps to conserve natural resources like minerals, water and wood ensures sustainable and optimal use.

Recycling cuts down amount of waste in landfill sites

Recycling old and used materials into reusable products enormously reduces the possibility of choking of landfill sites. This is beneficial because it helps minimize land and water pollution since landfills contributes mightily to environmental degradation.

Recycling ensures sustainable use of resources

Recycling guarantees that existing resources will be used sensibly and sustainably. The recycling process alleviates the possibility of discriminate use of raw materials when they are obtainable in huge supply. Governments these days have stepped in to encourage recycling from lower levels, for instance, schools, small-sized organizations and also at global levels. This means that manufacturing industries can leave existing natural resources for exploitation by our children in the future without affecting current production.

Recycling contributes to creation of jobs

To add to the benefits it brings to the environment; recycling opens up job opportunities. Recycling means many recycling plants will be set up, thus, leading to a long chain of collection and delivery. All these activities are performed by humans, so this will trigger an explosion of opportunities.

Reduces energy consumption

A lot of energy is used to process raw materials in the course of manufacture. Recycling plays a big role in reducing energy consumption, which is vital for large-scale production, for instance, mining and refining. Recycling also renders the whole process of production less expensive, which is a great victory for manufacturers.

Silicone Fluids

Silicone Fluid

Silicones are a family of inorganic polymers with Si – O – Si linkage, commonly known as poly(siloxanes). Most petroleum polymers have carbon atoms joined together forming polymeric chain while silicones have silicone atoms joined together with oxygen in between. It covers wide range of products with variety in its applications. One can notice difference  between Silicon and Silicones, as Silicon is a most common element in the earth’s crust and Silicones are synthesized inorganic polymers made out of it. Silicone fluids are generally colorless transparent liquids. They exhibit excellent resistance to heat, cold, and moisture. There is also little viscosity change in silicone fluids over a wide temperature range, and they have outstanding electrical properties. In addition, they are notable for their characteristics of mold-releasability, water repellency, lubricity, and defoaming properties

Features of silicone fluid

Silicones are available in wide range of properties from volatile liquids to soft gels, hard material. Silicones products provide solutions to ordinary and extraordinary problems. They make material stronger, more stable, more resilient, more aesthetically pleasing, easier to use or apply and longer lasting. They help materials perform to the high standards to cope up with consumers expectations. Silicones, being versatile, are high-performance materials which bring real benefits to a wide range of applications. This is primarily because of unusual properties such as thermal and oxidative stability & mild dependence of physical properties on temperature, high degree of chemical inertness, resistance to weathering, good dielectric strength and low surface tension.

Silicone Surfactant

Silicone Surfactants Surface active agents, or surfactants, are products that, at very low concentrations, markedly reduce the interfacial surface tension of liquid-gas, liquid-liquid and liquid-solid interfaces. Depending upon their behavior, at such interfaces surfactants can function as wetting agents, emulsifiers, detergents, dispersants, foaming agents, solubilizers, etc. and are therefore useful in many industrial applications.

Surfactants have two distinct components in their molecular structure: a hydrophobic (water-repelling) portion and a hydrophilic (water-attracting) portion. The combination of these distinct hydrophobic and hydrophilic parts within a single molecule accounts for the reduced surface tension and the other important properties that are characteristic of this group of chemical compounds.

Traditional surfactants have carbon chains as the hydrophobic portion of the molecule. The hydrophile that is added to the carbon chain will determine the solubility and the general class of surface active agents as anionic, cationic, nonionic or amphoteric.

A series of surfactants which are based upon silicone as a hydrophobe that contain other functional groups, similar to those seen in traditional surfactants have been and continue to be developed. In some instances, silicone is incorporated into a surface-active agent, with a polyoxyalkylene portion of the molecule and or a hydrocarbon portion of the molecule. As will become clear, this results in several unique properties of the surfactant. Historically, silicone compounds have been available as water insoluble oily materials.

Supreme Silicones is specializes in the creation of unique silicone-based surfactants, where the hydrophobic portion of the surfactant comprises a siloxane backbone. By adding various organic or inorganic functional groups, which by their nature may be nonionic, anionic, cationic or amphoteric (then referred to as organo-silicone compounds) to various siloxane chains or networks, Supreme Silicones can offer a truly endless variety of products with unique and desirable properties.


Silicone Surfactants are used as a Super Wetting and Spreading Agent, which have a low molecular weight, nonionic, developed to improve the wetting, spreading and penetration of agricultural chemicals.

As  Super wetting Agent reduces surface tension below 22 dynes/cm, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. Thus, complete coverage can be achieved with herbicides, insecticides, fungicides and other agricultural chemicals. It may be used as a formulation ingredient in pesticide products, or as a tank-mix adjuvant for foliar applied chemicals

Silicone surfactant, in addition to the rapid wetting and spreading action, also greatly increases the uptake of chemicals into plant tissues.

Potential Applications
