PA66 Vs. PVC

Abstract: Pa66 and PVC are both polymer materials, they each have unique properties and uses, so you can not simply say which is better. The following article HONY Plastic will make a detailed comparison in terms of material properties, application areas and usage scenarios to help you better understand the characteristics, advantages and disadvantages of these two materials.

1. Material properties

PA66 is a polyamide material with the advantages of high strength, good abrasion resistance, high temperature resistance, corrosion resistance and so on. It has good mechanical properties and can maintain stable performance over a wide temperature range. In addition, PA66 has good electrical insulation properties and chemical resistance. However, PA66 has high water absorption and is easily affected by humidity, so it requires strict drying treatment.

PVC is a polyvinyl chloride material with excellent processing performance, chemical resistance and electrical insulation properties.PVC products have good dimensional stability and weather resistance, so they are widely used in construction, automotive, electronics and other fields. However, PVC has relatively poor mechanical strength and high temperature resistance, and releases toxic gases when burned, so it needs to be used with caution.

2.Application areas

PA66 is widely used in machinery, electronics, automobiles and other fields, mainly used in the manufacture of gears, bearings, pumps and other high-strength, wear-resistant parts. In addition, PA66 can also be used in the manufacture of wire and cable insulation, network pipe and other electrical components.

PVC, on the other hand, is suitable for a variety of scenarios that require processing and molding, especially in the construction and automotive fields. In the construction field, PVC can be used to manufacture a variety of pipes and doors and windows and other building components, with excellent processing performance and chemical resistance; in the automotive field, PVC can be used to manufacture interior decorative parts and lampshades and other automotive components, with excellent processing performance and weather resistance.

3.What is the difference between pa66 nylon insulation strips and pvc insulation strips?

3.1 Different appearance

Pa66 nylon insulation strip color is darker, black, the surface of the frosted texture, printed products and other related information, product cross-section smooth and delicate.

Pvc insulation strip color to be lighter, usually gray-black, the surface looks smooth, no trademarks and other signs, product cross-section is relatively rough.

3.2 Different hardness

Pa66 nylon heat insulation strip is relatively soft, we can press the heat insulation strip with our hands to press it down, giving a sense of pliability, with a knife to cut the heat insulation strip will be relatively simple.

Pvc insulation strip is harder, press the hot strip by hand is very difficult to press down, with wallpaper to cut is also more difficult to cut, feel the material is very hard.

3.3 Different toughness

Pa66 nylon heat insulation strip flexibility is good, we force to stretch the heat insulation strip, the heat insulation strip can be stretched but will not break. Bend the heat insulation strip, not easy to be broken.

Pvc heat insulation strip flexibility is poor, we force to stretch the heat insulation strip, the heat insulation strip is basically not pull. When we bend the heat insulation strip, it will be easily broken.

3.4 Different flammability

Pa66 nylon insulation belongs to the flame retardant products, fire is not ignited, self-extinguishing from the fire.

Pvc insulation can be ignited by fire, and will emit plastic flavor after burning.

3.5 Window insulation strip how to choose

Window insulation mainly has two kinds of pvc and pa66 nylon insulation strip, we had better choose nylon insulation strip, its performance is relatively better. In the purchase of thermal strips, we can check the product surface is not the existence of white spots, floating fiber and other defects. We can also use a ruler to measure the size of a heat insulation strip, a good heat insulation strip size is accurate. We will cut off the insulation, observe the internal structure of the product, good insulation without air holes, tight structure and so on.
