- Material with CTI = 600V
To meet the high requirement of electronic industry, many product
requires CTI = 600V. There are two material in Dowell can meet this
requirement: Chang Chun Melamine Phenol molding compound MP185J and
Sumitomo DAP AM113. They have UL CTI of 1.
- These material is optimized for transformer bobbins. For more
information, please contact us.

- Ammonia-Free
Phenolic Molding Compound (PF) becomes the major material for
Hi-Tech components.
Technology has driven the size of product become smaller, especially
for electronic components. Electronic components and equipment
often require smaller size transformer coil bobbins. Some transformer
bobbins would be small enough to be SMT soldered on the circuit boards.
Regular phenolic molding compound (2 stages) will release Ammonia which
is hazardous and corrosive to the wire on the circuit and shortening the
electronic component life. Ammonia-Free Phenolic Molding Compound is 1
stage material which does not emit Ammonia gas. Such characteristic is
suitable for small or mini bobbins.
- Ammonia-free PF was initially widely used by Japanese company. And
now with the increasing of demand on quality world wide, more
bobbins and electronic manufacturers are using Ammonia-free PF as
raw materials.
-
- Sumidurez and Chang
Chun are producing Ammonia-free phenolic molding compound for
the market.

Glass Fiber reinforced PBT and Phenolic Molding Compound for
Automotive Parts
Automotive parts supplier is looking for the replacement for metal
material on automotive parts such as gear shift housing and gas pedal.
Engineering plastic is becoming the popular material for such
application.
- The replacement material such as thermosetting and thermoplastic
molding compound must have high physical properties, flexural
strength (~26,000psi or above), impact strength and heat resistance.
The advantage of using plastic molding compounds is the corrosion
resistance comparing with metal and longer life cycle fatigue. It can also be molded into new
design which steel was unable to be assembled before.
-
- Among those engineering plastic are fiber
reinforced PBT, fiber
reinforced phenolic molding compound and fiber reinforced PP.
Take Chang Chun PBT4130 (30%
fiber reinforced) as example, it can withstand 200oC or
above deflection temperature (ASTM D648). The flexural strength can
be reached 30,000 psi (ASTM D790). It can resist all major chemical
such as motor oil, gasoline, 30% sulphuric acid, Methane and Butane.
etc.
The parts include gear shift housing,
gas pedles, alternator housing, dash boards, gear housing, solenoid,
connectors etc.

- PBT Molding Compound gets new start in Dowell
- Phenolic moulding
compound has been always Dowell's major product and becoming very
successful in the engineering plastic market in China. Our main
suppliers include Chang Chun Petrochemical, Taiwan & Sumidurez,
Singapore.
-
- Starting from Mar.
01, 2001, Dowell will start to market another engineering plastic - Polybutylene
Terephthalate (PBT) moulding compound. And the manufacturer of
PBT is Chang Chun Petrochemical Ltd. As due to the fact that PBT
market is growing fast in China Market.
-
- Many China PBT users
may be heard of G.E. Valox, BASF Ultradur, Toray, Du Pont Crastin
and Celanex etc. While PBT from CCP* may seems new to PBT
users. However, per CCP official, CCP PBT has variety grade which is
equivalent to the world's major PBT brands**. Which means the
quality satisfaction and improvement are guaranteed. And most of
all, the price is reasonable - cost effective.
-
- Chang Chun PBT is
made in Taiwan.
