SWICOFIL - Yarn and fiber expert.


Swicofil is in a position to provide monofilaments in various 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. PBT 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 various. Not only is PVDF chemically inert to most acids and solvents. Furthermore, PVDF has excellent mechanical properties over wide range of temperatures, good abrasion resistance and low coefficient of friction, high continuous use temperature 150°C, an excellent UV and gamma ray resistance and an 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)
PPS distinguishes itself by the following properties:  continuous service temperature up to 240°C, inherently flame retardant (UL94 V0) and very good chemical and oxidation resistance. Also, PPS has a very low water absorption as well as a good hydrolysis and UV resistance.
