Q: What is the raw material used in the production of plastic products?: Cling film, plastic film are such materials, heat resistance is not strong. Usually qualified PE cling film will appear hot when the temperature exceeds 110 degrees, and will leave some plastic preparations which can not be decomposed by human body. And wrapped with plastic wrap food heating, food grease is easy to preserve the harmful substances dissolved in the film. Therefore, the food into the microwave oven before, to remove the cling film wrapped.

Q: What material is the disc made of, metal or plastic?: The compact disk is the carrier of functional structures (such as grooves, etc.), and its material is polycarbonate (PC), which has excellent impact toughness, large temperature range, good dimensional stability, weatherability and non toxicity.

Q: What kind of material is the raw material of plastic pipes?: Plastic pipe raw material is plastic particles, according to the pipeline production processing performance requirements, with the different requirements of finished products, there are different manufacturers grades, grades and performance differences.

Q: What material is plastic bag made of?: PVC-- polyvinyl chloride PVC referred to as PVC, the molecular formula for (CH2 - CH2CL) n, is the most important category of vinyl polymers, is currently the world's second largest plastic varieties after polyethylene. In China, the yield is the first in plastics. In the printing industry, packaging production of books, folders, tickets and other frequently used PVC calendered film cover color and transparent glazing film.

Q: What machines and materials are needed for the manufacture of disposable plastic cups?: The material required is PP, which is polypropylene.The machines needed are injection molding machines, shredders and dryers.PP plastic, chemical name: polypropylene, specific gravity: 0.9-0.91 g / cubic centimeter molding shrinkage: 1.0-2.5% molding temperature: 160-220 DEG C.

Q: What plastic material is resistant to high temperature?: As the high temperature resistant, anti-corrosion coatings, the coating can be used for a long time at 180 DEG C; the electrical and electronic industry for insulation partition, terminals, connectors, switches; machinery and machinery in the sticky dense pump, gear, piston ring blade tank, valve parts, watch parts, camera parts; car industry vaporizer. Distributor of electronic and electrical components, such as group parts, gas valve group, sensor of parts; home appliance parts have a tape recorder, structural components, products of various parts of the body diode; the other one is also used in aerospace, aviation industry, excellent heat resistance of the melting point of more than 280 DEG C, the heat distortion temperature above 260 degrees Celsius, long-term use temperature is 220-240 C.

Q: PVC what is the difference between raw and recycled raw materials?: Because the recycled material is a result of high temperature dissolved, it is likely to emit a pungent flavor, this odor may be harmful to humans.

Q: What are the raw materials needed for making plastic bags?: In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements. But this plastic bag is made from recycled material, which is environmentally friendly, and the price is 10% to 50% lower than that of the new material bag

Q: How to test plastic raw materials?: Thermal stability test of size and appearance quality. Place the product in a 8020C oven, 24H, and cool down to 2350C (2H). Measure the size of the same measuring point before and after the test, and calculate the percentage change rate. And observe the appearance quality changes, dimensional change rate of <0.2%, appearance is not allowed to have deformation, crack, expansion, surface gray, discoloration and other phenomena.

Q: What are the materials for making plastic basins? Are they raw materials?: Generally PP material, transparent is raw material, opaque is not necessarily
