What is the Rigid High Impact Polystyrene roll?
Ordinaryلفة بوليسترين عالية التأثير صلبة resin is an amorphous polymer.
The random arrangement of polystyrene macromolecular chains with benzene rings as side groups and large volume
with benzene rings as side groups determines the physical and chemical properties of polystyrene, such as high transparency High rigidity.
High glass transition temperature. Brittleness. Expandable polystyrene is made by impregnating a low-boiling physical foaming agent in ordinary polystyrene.
It is foamed by heat during processing and is specially used to make foam plastic products.
لفة بوليسترين عالية التأثير صلبة is a new type of polystyrene developed in recent years with good performance and belongs to engineering plastics.
لفة بوليسترين عالية التأثير صلبة is an impact-resistant polystyrene product produced by adding polybutyl rubber particles to polystyrene.
لفة بوليسترين عالية التأثير صلبةis a copolymer of styrene and butadiene, butadiene is a dispersed phase, which improves
the impact strength of the material, but the product is opaque.
Syndiotactic polystyrene has a syndiotactic structure and is produced using a metallocene catalyst.
This لفة بوليسترين عالية التأثير صلبةadds micron-sized rubber particles and connects the polystyrene and rubber particles together by grafting.
When impacted, the stress at the tip of the crack propagation is released by the relatively soft rubber particles. Therefore, crack propagation is hindered, and impact resistance is improved.
