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
