Polycarbonate (PC) Resin Used For Structural Parts, Nameplates And
Bezels
1. Description
Polycarbonate is best known for its impact resistance but has
additional properties like: Optical transparency, excellent creep
resistance, wide temperature range, high dimensional stability,
good electrical characteristics and self-extinguishing behavior.
Polycarbonate’s good heat resistance offers a high melt temperature
(it does require higher processing temperatures).
Polycarbonate is a tough, dimensionally stable, transparent
thermoplastic that has many applications which demand high
performance properties. This versatile thermoplastic maintains its
properties over a wide range of temperatures, from -40”F to 280”F.
It has the highest impact resistance of any Thermoplastic,
transparent up to 2” in special grades, outstanding dimensional and
thermal stability, exceptional machinability, stain resistant and
non-toxic while having low water absorption.
Machine Grade is relatively stress free to permit the most
demanding machining. It is also available in glass-filled. This
polycarbonate grade is perfect for high performance uses in tough
applications over a broad temperature range.
Window Grade is optically clear, providing total luminous
transmittance and a very low haze factor. The high impact strength
makes it resistant to repeated blows, shattering and spalling.
Glass Filled Grade Glass-reinforced polycarbonate is primarily
selected as a replacement for die-cast aluminum and zinc, when
these metals are being used and an upgrade is desired.
The coefficient of thermal expansion is reduced by nearly 75%, thus
equaling that of some metals. While glass-reinforced has less
impact strength than standard grades, it is still tougher and more
impact resistant than most other plastics and die cast aluminum.
2. Application
It is used for Medical components, Lenses, Equipment housings,
Electronics, Defense, Automotive, Lighting fixtures, Vehicle
windows, Structural parts, Nameplates and bezels, etc.
