general purpose polystyrene GPPS Transparent particles new plastic raw materials
1. GPPS characteristics
GPPS is a colorless, odorless, tasteless, glossy, and transparent particle. Lightweight, affordable, low water absorption, good adhesion, dimensional stability, good electrical performance, transparent products, and easy processing.
GPPS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones, and esters, but can only swell in acetone. It can withstand the action of certain mineral oils, organic acids, alkalis, salts, lower alcohols, and their aqueous solutions. Low water absorption, able to maintain its mechanical properties and dimensional stability in humid environments. Excellent electrical performance, high volume resistance and surface resistance, and unaffected by temperature and humidity changes, as well as corona discharge. The radiation resistance is also very good.
The main drawbacks of GPPS are brittle and easy to crack, low impact strength, poor heat resistance, and inability to withstand boiling water. It can only be used at lower temperatures and loads. Poor sunlight resistance, flammable. When burning, it turns black and has a special odor.
Application of PS
General grade polystyrene can be used for daily necessities, electrical, instrument casings, toys, lighting fixtures, household appliances, stationery, cosmetic containers, indoor and outdoor decorations, fruit trays, optical components (such as triangular prisms, lenses), window mirrors and molds, car lights, telecommunications accessories, electric frequency container films, high-frequency insulation materials, containers such as televisions, waveguides, chemical containers, etc. Suspension polymerization resin can be made into foam plastics with different densities, which can be used as heat insulation, sound insulation, shock prevention, floating, packaging materials, cork substitutes, pre foam body can be used as water filtering medium and light concrete, and low foam plastic can be made into synthetic wood for furniture, etc.
High impact polystyrene (HIPS) can be injected or extruded into a variety of products, suitable for household appliances, electrical appliances, instrument accessories, refrigerator lining, plates, televisions, radio recorders, telephone shells, cultural and educational supplies, toys, packaging containers, daily necessities, furniture, tableware, trays, tableware, structural foam products, etc.
Forming and processing of polystyrene (PS)
Polystyrene has good flowability, good processing performance, easy coloring, and good dimensional stability. Various parts can be processed by injection molding, extrusion molding, blow molding, foaming, hot forming, bonding, coating, welding, machining, printing, and other methods. Especially suitable for injection molding, materials can generally be used directly without drying during injection molding. But in order to improve the quality of the product, it can be pre dried for 1-2 hours in a 55 ℃~70 ℃ blast oven. The specific processing conditions are roughly as follows: the barrel temperature is around 200 ℃, the mold temperature is 60-80 ℃, the injection temperature is 170 ℃ to 220 ℃, and the injection pressure ratio is 1.6-4.0. The formed product should be treated at a constant temperature of 70 ℃ for 2-4 hours in an infrared lamp or blast oven.

Ningbo Changhong Polymer Scientific and Technical Co., Ltd. invests in the construction of "600,000 tons/year PBAT/PBS/ PBT flexible production project in a fully biodegradable thermoplastic industrial zone" in two phases, with 300,000 tons/year in each phase and a total construction period of 5 years. In the first phase, a production line of 100,000 tonnes/year will be built first, which can flexibly produce different products such as PBAT, PBS and PBT according to the market demand, and also has the ability to expand and modify the chain to produce other different grades of products. The first phase of the project is expected to have an annual output value of RMB 2 billion and an annual tax payment of RMB 120 million.
