Our Company
Suzhou Polywell Engineering Plastics Company is located in the
city of Zhangjiagang, Jiangsu Province, China. We have been making
research and development for special material of PA66 thermal
insulation strip since 2006.We have a deep understanding and rich
experience of the relevant industry during this year.
We expanded our business scope since the year of 2010. We not only
produce PA66 granules and PA66 thermal barrier strips, but also
sell parallel twin-screw granulator, extruding machine, mould and
production technology.
we are developing overseas market. We are going to promote our
products all around the world, to seek win-win cooperation, mutual
benefits and mutual development with our customers.
Product Introduction
Nylon/PA66 granules reinforced by fiberglass, with special
additives,is blended and extruded by twin screw extruder. It is
more suitable for extrusion of thermal break profile.Compared with
ordinary granules, it is more conducive to forming.It has certain
advantages in speed,surface finish and yield.The performances of
nylon thermal break profiles which are made from this material can
meet the national standard of China. 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.
Advantage
1. High mechanical strength,high toughness,high softening point.
2. Good wear resistance,self-lubrication,long-term work at high
temperature.
3. High CTI value,excellent electrical insulation,low smoke.
4. Fast crystallization,fast forming,high temperature resistance.
5. Anti-ultraviolet radiation,anti-chemical agent corrosion.
6. High yield,easy start-up,and get less scrap in the early
start-up stage.
7. No lack or incomplete of profiles in the production process.
8. There are different formulations for different shapes.

Application
It is mainly used for nylon extruding profiles and nylon thermal
break extruding strips. The granules produced by our company are
special materials for nylon extruding profiles.There are different
formulations for different shapes and complexities to ensure the
smooth production of nylon profiles.
