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 material do you need for plastic film? Do you use this material?: Plastic bags, quality, food grade requirements, the use of brand new HDPE (low pressure polyethylene).

Q:What are the raw materials for producing plastic bowls and cups?: Now the plastic bowl is basically made of PP, the quality is better. What's more, the PP bowl can be baked in a microwave oven, and other plastics will not.

Q:What are the heavy bags in the plastic material?: Plastic raw materials in the heavy bag refers to high pressure polyethylene (LDPE) is a kind of special, for the production of plastic packaging bags, the plastic bags bearing force and pulling force are high, and have a high degree of transparency, plastic raw materials sales is often called the heavy bag material, melting point to: 0.3

Q:Does plastic raw material ENBA have toughening effect?: EMA can be used as toughening agent for alloy such as PBT/PC and PC/ABS.

Q:What does MFI mean in PC material?: MFI- melt flow index, also known as the melt flow rate (MFR), it was determined at a given shear stress (with applied load) and temperature, melt flow properties of materials (measured by g/10min).

Q:What is the disposable transparent plastic cup?: PMMA: commonly known as acrylic, transparent material, its surface hardness is slightly lower, easy to wipe flowers. It is suitable for making transparent insulation parts and general strength parts

Q:What plastic materials need to be dried for injection molding products?.. How much is the temperature?: Plastic particles, such as water, are evaporated in the pre heating process of the injection molding machine and then condensed in the cooling molding process, which acts as (Yin Si) in the product and affects the quality of the product.

Q:What are the raw materials for vest plastic bags?: Shrink film (Shrinkfilm) is a thermoplastic film that is stretched in production, directed, and contracted by hot air treatment or infrared radiation during use. After heat treatment, the film is wrapped tightly in the package, and the shrinkage force reaches the maximum value in the cooling stage and can be stored for a long time.

Q:What raw materials do plastic color printing plants use?: Mainly plastic film and ink, the film is generally in accordance with the nature and requirements of products such as PVC film, POF film
