The Elastomeric Modifiers business unit manages two product lines : Chemigum^® elastomers and Sunigum^® elastomers.

Since the 1970's, innovative grades of these elastomers have been regularly developed in the R&D centers in Europe and the US to cater to the evolving needs of our customers. Investment in production facilities have been made to introduce new processes, maintain healthy practices of industrial safety and hygiene, modernize packaging for easy handling, disposal and recycling, and, of course, to add capacity to meet the growing worldwide demand.

This growing demand plays a role in pioneering our "Materials" as it does to aim our philosophy of working with our customers on new "Concepts". The overall goal is to satisfy the needs of our customers efficiently and economically. We participate with our customers to convert concepts into business by providing guideline formulations and other technical services, joint promotions and assistance in identifying new markets for their products.

CHEMIGUM® ELASTOMERS Chemigum NBR elastomers, copolymers of acrylonitrile and butadiene, are known for their good mechanical properties and resistance to fuels, fats and oils. In blends with PVC, Chemigum elastomers enhance physical properties and chemical resistance. In addition, they help minimize loss of liquid plasticizers due to extraction, volatility or migration, thus maintaining flexibility under harsh conditions. Chemigum elastomers are also widely used in friction material compositions in which they contribute significant advantages in both processing and performance. Different Chemigum grades have been developed in powder form to meet specific processing or end-use requirements.

SUNIGUM® ELASTOMERS Sunigum elastomer is a precrosslinked, acrylate terpolymer with functional carboxylic groups. Is is intrinsically resistant to degradation by heat and UV radiation, and to many chemicals including oils & fuels. Its novel composition and structure make it compatible with a wide range of polar resins: PVC, CPE, COPE, TPU, ASA/ABS/SAN and other polymers with some polarity such as ethylene copolymers (EVA and EMA provided the co-monomer content is at least 20%). Although Sunigum is not directly compatible with non polar resins, it can be blended with polyolefins through reactive compatibilization techniques, for example using glycidyl containing ethylene copolymers as compatibilizers. Sunigum's basic properties and flexibilizing potential allow users to tailor-make softer grades of general-purpose and engineering grade thermoplastic elastomers where aesthetics, color-retention and weatherability are of prime importance.
