Yarn/Textiles

Textile-Based Yarns & Monofilaments

Piles and Yarns

Can be made from a wide range of materials
(Thermoset and Thermoplastic)
Piles typically used in applications that require a soft fiber that can adjust to irregularities on the sealing surfaces at a low closing force
Excellent in sliding applications.

Monofilaments

Individually extruded filaments made from thermoset and and thermoplastic materials
Monofilaments are typically used in applications that require a more resistant sealing member with a higher closing force and compression set resistance.
Sizes Ultrafab uses range from .004″ to .016″

Commonly Available Materials

Polypropylene

General Specifications of Polypropylene:

• Medium melting point (320° F)
• Generally less expensive than Nylon
• Excellent resistance to acids, alkalis, oil and grease
• Lower bend recovery and compression resistance than Nylon
• Lower flex fatigue and abrasion resistance than Nylon

Nylon

General Specifications of Nylon:

• Offers premium bend recovery and compression resistance
• Flex fatigue and abrasion resistance
• Good resistance to alkalis, oil and grease
• Excellent resistance to mildew – premium Nylons work well in heavy moisture conditions
• Superior UV stability (untreated) compare to UV stabilized Polypropylene
• Higher melting point than Polypropylene (450° F)
• Generally more expensive than Polypropylene
• Poor resistance to acids
