Petrolatum Wax
Petrolatum waxes are natural, mineral waxes from petroleum that are microcrystalline in nature and a semi-solid at room temperature. The waxes themselves are non-reactive, non-toxic, biodegradable and compostable products with many applications where barriers are required to liquids and gases e.g. lotions, candles and rust preventatives.
Primary Antioxidants
These products act as free radical scavengers and are used to protect the finished product from thermal degradation and oxidation, leading to long-term stability as it is able to extend product lifetime and aesthetics in their working environmental conditions. Metal Deactivators are available to be used when the polymer is in contact with metal ions (e.g. copper).
ROKAmer®
The ROKAmer® product line represents a group of non-ionic surfactants of the EO/PO block copolymers. Most of the ROKAmer® products are block copolymers in which the central polypropylene glycol group is flanked by two polyethylene glycol groups. Block copolymers are multipurpose products used in a variety of applications where antifoaming, dispersing and wetting properties are needed. Applications include detergents, I&I applications, rinse aids, hard surface cleaners, metal cleaners paints and coatings, water treatment and others.
ROKAnol® series
The ROKAnol® range is comprised of a wide variety of non-ionic surfactants that are ethylene and propylene oxide adducts to various types of alcohols.
Secondary Antioxidants
These products are peroxide decomposers and are incorporated into the polymer, preventing degradation during processing.
STEPANPOL® Polyester Polyols
Stepan offer a wide range of aliphatic and aromatic polyester polyols for the coatings, adhesive, sealant and elastomer market. Stepan also offer a custom manufacture service for polyester polyols.
SUPRASEC® MDI and MDI-based Prepolymer
SUPRASEC® MDI is a high performance raw material with applications across a variety of markets including wood-care, textile and leather, plastics, marine/offshore, electrical, aircraft, automotive and construction. Cost effectiveness, versatility, ease of use and superior physical properties make SUPRASEC® MDI an ideal product for use in adhesive, coating and elastomer applications.
UNITHOX ™ Ethoxylates
UNITHOX ™ Ethoxylates are nonionic emulsifiers and wetting agents with high molecular weights and melting points. These are fully saturated, long chain, linear, C20 to C50 synthetic alcohol ethoxylates. As a result, they can disperse higher molecular weight polyethylene, polyolefin, paraffin waxes and serve many applications including paints, coatings, inks, plastic, and agriculture.
UV Absorbers
This range provides protection by absorbing UV radiation, then dissipating it as thermal energy. UVAs can be used in combination with HALS to provide optimum protection of the product.
UV Blends
Blends of UV stabilisers, tailored for specific applications or to customers' needs.
