DESCRIPTION
SEPS is formed by selective hydrogenation of styrene and isoprene copolymer. Compared with SEBS, SEPS elastomer has fast oil absorption speed, low surface viscosity after oil absorption, high hardness and tensile strength, small permanent deformation at break, and good adhesion to various polar and non-polar materials.
The combination of SEPS YH-4053 and 4051 and 4052 will show different touch and bonding, and the transparency will not change. SEPS YH-4053 grades can also be used for medical products, TPE granulation and adult products.
APPLICATION
Food devices
medical products
