Which price is higher, POM or F4?
POM, commonly known as Saigang, is a very common plastic, and its price is relatively low, except for POM with other additives. F4, short for PTFE, that is, polytetrafluoroethylene, is a high-temperature plastic, and the relative price is higher. But the price of the mixture of POM+F4 is higher than that of F4 The performance of the two is not the same, depending on your actual processing requirements for material performance.

How to eliminate shrinkage holes in pom injection molded products
POM material, also known as Saigang, special steel, because this material is tough and elastic, it is a kind of thermoplastic engineering plastic with high density and high crystallinity Due to its high crystallinity, the shrinkage rate of POM material is quite large, which can reach 2%~3.5%. Therefore, shrinkage and shrinkage of this kind of plastic products are more common, and shrinkage occurs in the areas where the product is relatively thick. The injection adjustment can be improved and it is difficult to eradicate. Perhaps it can be adjusted from the mold struc

Are automotive plastic parts resistant to high temperatures? What is the minimum degree?
The specifications of parts and components in automobiles are defined by special regulations, which are different from ordinary industrial regulations. Plastic parts have different equivalent requirements according to the dressing position. Generally, exposed parts (such as internal sound surface, external quick plastic seals) are -40 to 105 degrees Celsius. Some car manufacturers have reduced the low temperature to -30 according to the actual sales. Degrees, the high temperature eased to 85 degrees. Please send inquiry and drawing to sales@h

ABS: Commonly known as engineering plastic, it can be used for connectors, seat backs, and seat plates. It is the main raw material for electroplating (water plating) in plastics. PP: Commonly known as polypropylene, used for five-star feet, armrests, foot pads and connectors with low strength requirements. Disadvantages: poor wear resistance and low surface hardness. PVC: Commonly known as polyvinyl chloride, mainly used for edge banding and insertion conditions. It is suitable for extrusion molding. At the same time, PVC material is a non-combustible material in plastic part

What are the types of plastics?
1. Polyethylene: Commonly used polyethylene can be divided into low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact properties, film-forming properties, etc. 2. Polypropylene: Relatively speaking, polypropylene has more varieties, more complex uses, and various fields. The varieties mainly include homopolypropylene (homopp), block copolymer polypropylene (copp) and random copolymer polyprop
What are the structures of thermosetting plastics and thermoplastics?
Thermosetting resin is used as the main component, combined with various necessary additives to form a plastic product through a cross-linking and curing process. In the early stage of the manufacturing or molding process, it is liquid. After solidification, it is insoluble and infusible, nor can it be melted or softened again. Common thermosetting plastics include phenolic plastics, epoxy plastics, amino plastics, unsaturated polyesters, and alkyd plastics. Thermosetting plastics and thermoplastics together constitute two major components in synthetic plastics.

The so-called explosion refers to: in a short period of time, a large amount of energy is generated in a certain space, which makes the space unbearable and causes an explosion. However, PVC itself has good flame retardant properties and is often used as a fireproof material, which limits the conditions for it to generate a lot of heat in a short time, so it will not mix with the material (don't mix explosives) to produce explosive. In addition, the mixture of POM steel material and PVC will not explode. Please send inquiry and drawing to sales@honyplastic.com
