Friends, do you know? Now the market is mixed, there are some black-hearted manufacturers who use the raw materials of PA66GF25 insulation strips, which are made of a low-quality PA6 raw material. What they do is single 6 insulation strips. Do you know PA single 6 insulation strips and PA double 6 insulation strips? How much is the gap between the heat insulation strips? Although it can't be seen on the surface, the difference is very big. The first one is the difference analysis and comparison.

1. High temperature resistance.

PA6 heat insulation strip can withstand high temperature of more than 100 degrees, and can not be sprayed back

PA66GF25 heat insulation strip can withstand high temperatures of more than 240 degrees, and can be sprayed back

2. Linear expansion coefficient

The linear expansion coefficient of PA6 insulation strip is very different from the linear expansion coefficient of aluminum alloy (the effect of thermal expansion and contraction cannot be achieved)

PA66GF25 thermal insulation strip has the same linear expansion coefficient as aluminum alloy (can ensure thermal expansion and contraction)

Three, three major properties (airtight, watertight, wind pressure resistance)

PA6 heat insulation strip can not play the three major performance functions due to material defects.

PA66GF25 heat insulation strip can play three major performance roles.

4. Tensile strength and aging resistance

PA6 heat insulation strip does not meet the national standard, the transverse tensile strength is 70/MPA, and it is easy to age

The horizontal tensile strength of PA66GF25 heat insulation strip is above 80/MPA, durable and not easy to aging

Five, heat insulation, heat preservation, sound insulation performance

PA6 heat insulation strip can't reach the three performances

PA66GF25 insulation strip can achieve three performances.

Tests have proved that the installation of PA6 (single six) insulation strips on PA6 does not meet any standards and has no effect.

PA66GF25 heat insulation strip; is a series of modified engineering plastics synthesis, it has a high melting point, excellent heat resistance and self-extinguishing. However, the unmodified PA66 material does not match aluminum alloy in terms of tensile strength and linear expansion coefficient. Through experiments, adding 25% glass fiber to PA66 is modified into engineering plastic as the basic material of heat insulation strip. , It is that there is no new material for heat insulation strip that is more reasonable and economical than this.

Friends who have solved so much, would you still choose PA 6 heat insulation strips for a cheaper price? PA6 (single six) heat insulation strip can be said to be unable to achieve any effect, so how do you know if it is PA6 (single six) insulation strip? The first is the price, its price is very different from PA66GF25 heat insulation strip, the second can be burned with fire, PA6 (single six) use fire to smoke, PA66GF25 heat insulation strip does not smoke. How to choose a manufacturer of PA66GF25 insulation strips? Tianjin Ruifeng Rubber & Plastic Products Co., Ltd. is an enterprise that produces PA66GF25 heat insulation strips, with an annual output of 220 million meters of PA66GF25 heat insulation strips. Buying heat insulation strips to Tianjin Ruifeng Rubber & Plastic Products Co., Ltd. is your wise choice.

Tianjin Ruifeng Rubber Products Co., Ltd. is looking forward to cooperating with you: 15922244128 (same number on WeChat)
