Swicofil is
in a position to provide also monofilaments in new materials. In all these
specialities there is never stocks and no samples. Production only on
special demand of customers. Minimum order 400 - 500 kgs
PBT - polybutylene terephthalate -
density 1.32
Compared to polyester this polymer has
better properties of abrasion resistance, loft and dimensional stability.
It has a very low moisture absorption (0,15% at 20°C 65% R.H.), a good
resistance to chemical and outdoor exposure agents and good electrical
properties. The UL-94 V0 version is commonly used for braided hoses in
electric cabling and automotive industries.
POM - polyoximethylene - density 1.41
Due to its very good resistance to fuels
and chemicals this type of monofilaments is mostly used in the production
of filter fabrics for automotive use. Other features of this resin are
high stiffness, high mechanical strength even at very low temperature, low
water absorption and good dimensional stability at high temperatures
PA 12 - polyamide 12 - density 1.01
Its lower specific weight - compared to PA
6 and 6.6 - combined with its good chemical and abrasion resistance make
this monofilament the best choice for several application in wet
filtration. Due to its comparable properties it is the only alternative to
PA 11 (Rilsan B)
PVDF - polyvinilidene fluoride -
density 1.78
Main properties of this polymer are:
- Chemically inert to most acids and
solvents
- Excellent mechanical properties over
wide range of temperatures
- Good abrasion resistance and low
coefficient of friction
- High continuous use temperature 150°C
- Excellent UV and gamma ray resistance
- Excellent fire resistance (UL94 V0)
- Due to its higher performance and cost
this monofilament is used just on very special applications.
PPS - polyphenylene sulphide -
density 1.35
- Continuous service temperature up to 240°C
- Inherently flame retardant (UL94 V0)
- Very good chemical and oxidation
resistance
- Very low water absorption
- Good hydrolysis resistance
- Good UV resistance
