Fiber Glass Filled Nylon 66 Granules With 1.25G / Cm3 Density For
Insulating Strips
Introduction:
Polyamide 6.6 granules reinforced by fiberglass, with special
additives, is blended and extruded by twin screw extrusion machine.
It is more suitable for extrusion of heat insulation strip.
Compared with ordinary granules, it is more conducive to forming.
It has certain advantages in speed, surface finish and yield. The
performances of nylon insulating strip produced made of this
material meet the national standards. It can not only be customized
according to customer requirements, far exceeding the national
standard, but also can add high-efficiency flame retardant to
achieve the purpose of flame retardant.
Why use polyamide to produce thermal break profiles?
Polyamides offer high levels of heat resistance, stiffness and high
mechanical stability for a durable solution. Our special glass
fiber reinforced PA 66 GF25, dry impact resistant mixture is ideal
for the production of structural and reinforcement profiles.
Offering excellent heat resistance, polyamides can be used in the
toughest of conditions, for example exposure to hot and humid
environments. PA profiles can drastically reduce the Utj (U-Value
of a thermal joint), which insulates the energy flow from the
outside of the facade to the inside.
The uncomplicated processing of polyamides is another key benefit.
With various properties that can be individually adapted according
to the specific project and need, polyamides are the perfect choice
for the manufacture of special extrusion profiles.
What is GF in plastic material?
Glass-filled nylon is a synthetic polyamide thermoplastic and it's
one of the most important materials used in engineering thanks to
its strength and heat resistance. It's made by adding powdered
glass to nylon resin or by extruding the plastic with glass fibers.
Application:
Specially used in thermal break strips, thermal bridge, heat
insulation bar, etc.
