What is HIPS Plastic？

HIPS Plastic Introduction

HIPS plastic is called impact-resistant polystyrene, which is an impact-resistant polystyrene product produced by adding polybutyl rubber particles to polystyrene.

HIPS plastic adds micron-sized rubber particles and connects polystyrene and rubber particles together through grafting. When hip plastic is impacted, the tip stress of crack expansion will be released by relatively soft rubber particles, so the crack expansion is hindered and the impact resistance is improved.

HIPS plastic is usually transparent and colorless, and can be colored as required when used.

HIPS Plastic Features

1. Excellent mechanical properties: HIPS plastic has high strength, high toughness, fatigue resistance, corrosion resistance and other mechanical properties. It can be used in large household appliances, automobiles, sports equipment and other fields, and has important material advantages.

2. Excellent processing performance: HIPS plastic can be processed into complex shapes through blow molding, injection molding, extrusion and other methods, so it is widely used in the manufacture of consumer products.

3. Excellent molding performance: HIPS plastic can be molded by various methods, including hot press molding, thermal transfer molding, vacuum molding, etc., and can be used in stationery, toys, household daily necessities and other fields.

HIPS Plastic Advantages

1. Safety and environmental protection: HIPS has excellent durability, fire resistance and electrical insulation. It is regarded as a safe and environmentally friendly plastic and is widely used in medical, food and other fields.

2. Easy processing: Due to its excellent processing performance, manufacturers can easily transform HIPS materials into finished products of various shapes, providing more options to suit the needs of different fields.

3. High economic benefits: Compared with other materials, HIPS materials have lower costs, making it easier for manufacturers to achieve cost control.

HIPS Plastic Disadvantages

1. The rubber content in HIPS plastic is 15%, which interferes with its fluidity to a certain extent.

2. The cooling speed of HIPS plastic is very slow. In addition to sufficient pressure maintenance time and speed, the mold must also have excellent heat exchange function to reduce part shrinkage and shape change after mold release.
