Ultrasonic Welding Material PC And PS

Polycarbonate (PC for short) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonates have been industrially produced. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five major engineering plastics.

Application areas of PC:

The application and development of polycarbonate is developing in the direction of high compounding, high function, specialization and serialization. At present, various products such as optical discs, automobiles, office equipment, boxes, packaging, medicine, lighting, films and other products have been launched. grade number. Widely used in building materials industry, automobile manufacturing industry, medical equipment industry, aerospace industry, packaging industry, electronic and electrical industry, optical lens industry and optical disc industry.

Polystyrene refers to a polymer synthesized by free radical polycondensation of styrene monomer, the English name is Polystyrene, referred to as PS. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100 degrees Celsius, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

Application areas of PS:

GPPS-525 general-purpose grade: medium flow, high transparency, good overall performance, in line with food hygiene standards, widely used in the outer packaging of audio and video products, handicrafts, food packaging, decorative boards, stationery, tableware and other industries.

GPPS-535 injection molding grade: high strength, high heat resistance, high transparency, in line with food hygiene standards, widely used in home appliances, building materials industry, food packaging materials, etc.

HIPS-688 injection molding grade: high impact resistance, high heat resistance, low temperature resistance, good rigidity, in line with food hygiene standards, widely used in home appliances (various electrical parts, air conditioners, TV sets, telephone casings, computer keyboards, host panels ), medical supplies, lamps, toys and other industries.
