FAQ

Does plastic raw material ENBA have toughening effect?

Both of them are similar, because they are polar and elastic, so they can be used as toughening agents in plastics. The price should be high. There are strong polarity of grafted materials, such as ST-1 and other toughening agents, moderate price, high performance price ratio.

How to use all kinds of plastic materials?

AS (SAN) acrylic styrene transparent adhesiveAS is acrylonitrile (A), styrene (S) copolymer, weather resistant medium, not by the high humidity environment, ability, general oil, detergent and mild alcohol, poor fatigue resistance, not easy to crack due to stress, material quality high transparency, good liquidity in ABS.Suitable plastic products: tray, cups, cutlery, toothbrush, refrigerator cabinet, knob, lighting accessories, accessories, instrument mirror, packing box, stationery

What are the raw materials of foam plastics and how do they come out?

The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.

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.

What are the main biodegradable plastic bags made of?

The degradable plastic bags made of polyethylene and starch, but this can only be degradable plastic plastic degradation into smaller chunks of plastic, plastic compositions did not completely disappear, so its degradation is limited.

Main ingredients and formulations of PPR tubes

PP-R (polypropylene, random) tubes are also called type three polypropylene tubes and also called random copolymerized polypropylene tubes or PPR tubes. The main component is polypropylene three. The formula is different for each manufacturer. This ratio requires manufacturers to do experiments many times before they can be certain.

What are the specific differences between plastics and plastics?

Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and outstanding performance.

What do you mean by grade 1, class two or class three in plastic?

Three grade material refers to the raw material has been used two times or more times, the processing of particles, and its elasticity, toughness and other aspects are not very good.
