What is plastic PS?

PSplastic,PS(polyStyreneDepartment of plastic) meansmacromolecular chainIncluding styrene-based plastics, including styrene and itsCopolymer, specific varieties include ordinary polystyrene (GPPS£©¡¢High Impact Polystyrene£¨HIPS£©¡¢Expandable polystyrene£¨EPS)andShigeru metalpolystyrene£¨SPS)wait.PSIt is widely used in the optical industry because of its goodTranslucencycaused by, can manufactureOptical glassand optical instruments, also transparent or brightly colored, such aslampshade, lighting equipment etc.PSIt can also produce many electrical components and instruments that work in high-frequency environments. becausePSPlastic is a difficult inert surface material, and it needs to be used professionally for lamination in industry.PSgluebonding.Guangzhou Auto Engineering Plastics Co., Ltd., your professional PS consultant!

plasticFeatures of PS

1.Environmental friendly
£¬Recyclable, no harmful substances, no smell, no pollution, green and environmental protection

2.The finished product hasdiversity

3.Products can be madecycle
£¬recyclable.

4.The light transmission effect is good, and the light transmittance can reach88%-92%¡£

5.Glossy surface, easy to stain, has a good aesthetic decorative effect

6.High hardness, good rigidity, relatively strong and durable

7.Good water resistance, not easy to damage when soaked in water;

8.Good chemical corrosion resistance, not easy to decompose and damage;

9.Colorless, tasteless and odorless.

plasticProcessing technology of PS

1.injection molding

Ordinary injection molding machine can be used, and the thickness of the product is2.3¡«3 mmIn the range, the limiting flow length and thickness ratio is200£º1, the draft angle is not less than1¡ã, the depth of the exhaust vent groove is less than0.03mm, the temperature difference between the two dies is less than3¡«6¡æ. The specific injection molding process conditions are: molding temperature180¡«215¡æ, injection pressure30¡«150MPa, the mold temperature is lower than70¡æ¡£

2.extrude

It can be processed on an ordinary extruder, and the extruded products include pipes, rods, sheets, films, fibers, etc. It has low strength and brittleness when it is not stretched after molding, and its transparency, gloss, strength and toughness are all significantly improved after stretching.PSThe extrusion molding temperature is150¡«200between ¡æ.

3.foam molding

useGPPSFoaming agent is divided into chemical foaming agent and physical foaming agent. Using one-step extrusion, the foaming agent andPSMix well or inject physical blowing agent in extrusion melting sectionPSIn the melt, extrude, foam and cool. useGPPSThe foamed plastic has the advantages of fine cells and high strength.

The difference between ABS plastic and PS plastic

1£©different in nature
?1¡¢PSPlastic: A class of plastics including styrene base in the macromolecular chain, including styrene and its copolymers, and specific varieties include ordinary polystyrene(GPPS), High Impact Polystyrene(HIPS), Expandable polystyrene(EPS)and metallocene polystyrene(SPS)wait.
?2¡¢ABSPlastic: Acrylonitrile(A), butadiene(B), styrene(S)Terpolymer of three monomers, the relative content of the three monomers can be changed arbitrarily to make various resins.
2) with different characteristics

1¡¢PSplastic:
1)Mechanical properties: high strength, fatigue resistance, dimensional stability, low creep(Little change in high temperature)¡£
2)Heat aging resistance? ?

3)Solvent Resistance: No stress cracking.
4)Water stability: easy to decompose when meeting water(Pay attention when using in high temperature and humid environment)¡£
??2¡¢ABSplastic:
1)Good overall performance, high impact strength, good chemical stability, good electrical performance;
2)Good fusion with plexiglass, can be made into two-color plastic parts, and the surface can be chrome-plated and painted;
3)There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other grades;
4)good flexibility;
5)It is suitable for the manufacture of general mechanical parts, wear-resistant parts, transmission parts and communication parts.

plasticApplication of PS

1, Production of electronic appliances: connectors, switch parts, household appliances, accessories parts, small electric covers.

2, As the parts of the car, there are mainly exterior parts, mainly corner grille, engine heat release escutcheon, etc.; internal parts, mainly include endoscope stays, wiper brackets and control system valves. Automotive electrical parts, such as automotive ignition coil strands and various electrical connectors, etc.

3, Production of machinery and equipment: belt drive shafts of video tape recorders, electronic computer covers, mercury lamp covers, electric iron covers, baking machine parts and a large number of gears, cams, buttons, electronic watch cases, camera parts (with heat resistance, flame retardant requirements)

4, used in the optical industry
It can be used in the optical industry to make optical glass and optical instruments, and can also be used to make lampshades and lighting equipment of various colors.
5, Applied to the building materials industry
The raw material for making resin tiles.
