505A is an amorphous rubber with low molecular weight and high ENB content. 505A is able to be applied for various types of product by taking advantage of its good flow and high cure rate. By blending with diene type rubbers such as a natural rubber, 505A plays significant roles to improve their ozone resistance. 505A is also suitable for foam applications made by continuous curing and it produces various sponge products with low density. Applications: Electrical equipment, Sponge products (Weather strip, Heat insulated pipe etc.), Ozone resistance modifier

512E is a semi-crystalline rubber with medium molecular weight and high ethylene content. 512E shows high green strength of uncured rubber and also its compound provides outstanding physical properties. 512E also has its polymer design suited for the extrusion process. Excellent processability and articles with good shape retention are promised. Applications: Extrusion products (Hose, Window gasket), General industrial products

552E is a non-oil extend grade with high molecular weight. 552E can offer high filler and oil loading formulations which contribute to have cost saving compounds. Applications: Extrusion products (Hose, Window gasket), General industrial products
