Products Introduction

SINOSAB   YDC™ Polybutadiene Rubber(BR) presents flexibility and good abrasion resistance, aging resistance, good low temperature resistance and excellent dynamic heat load is small, easy-to-metal bonding.Operating temperature range: about -60 ~ +100 °C.

Products Application

SINOSAB YDC HDPE is suitable for many plastic molding methods. Blow molding can be used for making various types of bottles, cans and industrial tanks and barrels. Injection molding is used for making various containers and goods of daily use, such as basins, barrels and baskets and furniture. Extrusion molding is used for making pipes, strapping tapes, fibers and single filaments and can also be used for making wires & cables covering materials and synthetic paper. After a large amount of inorganic filler is added, HDPE can also be used as an alternative to timber and cardboards for making calcium plastic packing containers, furniture, doors and windows.
