High-temperature Thermal insulation gasket
Technical data
The plastic extruder pelletizing template adopts a centralized multi-channel oil (steam) heating method and is equipped with heat insulation and waterproof seal to ensure that the discharge hole can be discharged normally at the set temperature.
The granulation die plate works under the temperature of 60 ℃ -70 ℃, and its heat loss rate is very high. Therefore, the performance of the heat-insulating and waterproof gasket material will directly affect the effectiveness of the template underwater.
JF · 300 is a modified PTFE (polytetrafluoroethylene) material, which is highly compressible.
The raw material of the thermal insulation and waterproof gasket is special ceramics and mineral fiber. It is composed of filler and adhesive material.
It has high-temperature resistance characteristics. Because of the small thermal conductivity, the thermal insulation is very excellent.
At the same time, it can keep chemical stability in almost all strong acid and alkali solutions, can withstand high temperature and very small thermal conductivity, which determines the application scope of JF · 300 heat insulation waterproof gasket as thermal insulation material, and can meet the multi-purpose gasket of chemical and petrochemical, coal chemical, steel and iron industries. At the same time, it is also special thermal insulation and waterproof gasket material for granulation die plate of the plastic extruders.
