Principal Products**

Apec® is the brand name for an advanced copolycarbonate. With its unique combination of high heat reistance, thoughness, transpareny  it is unlike any other engineering thermoplastic. These properties, along with good dimensional stability, weatherability and flowability, allow Apec® to be utilized as a replacement for glass, metal or standard polycarbonate in high-heat applications

Bayblend® is the trade name used by Bayer for its product line of amorphose, thermoplastic polymer blends based on polycarbonate (PC) and acrylonitrile butadiene styrene (PC+ABS blends)  as well as acrylonitrile styrene acrylate (PC + ASA blends). Their property profiles ca be customized by varying the compsition of the blend. The particular strengths of Bayblend® are its balanced combination of heat resistance, toughness ans stiffness and its excellent processing characteristics. The unique combination offers an ideal conolidation of mechanical and thermal properties for appliances, automotive and transportation, electrical, consumer products, medical, electronics, IT and communication applications.

Brand name for high quality polyurethane dispersions as film formers and powder as sensory additive for cosmetic formulations
