Substrates

Substrates

Trelleborg offers a wide variety of substrates – from Kevlar® to silk – providing possibilities to perfectly match material properties to specific applications needs. The choice of weaving method adds another aspect of customization towards the final high-performance, application-specific engineered fabric.

Selected substrates

In addition to the traditional consumer products, manufactured fibers / substrates are used in many less obvious ways and new applications arise continually. Below are examples of substrates we offer and an introduction to common uses:

Common Name(s)
Substrate / Fiber Characteristics Common Substrate / Fiber Uses
Tensile strength (MPa)
Elongation at beak (%)
Specific gravity

Aramid

• High strength-to weight, high tenacity and high modulus.
•Low elongation and creep.
• Good abrasion resistance.
• No melting point (degradate) and low flammability.
• Nonconductive.
• Resistant to organic solvents, sensitive to acids, salts and UV.

Flame-resistant clothing, protective vests and helmets, composites, asbestos replacement, hot air filtration fabrics, tire and mechanical rubber goods reinforcement, ropes and cables, sail cloth, sporting goods.

Carbon
• High strength and modulus, low weight.
• Heat and flame resistant.
• Impact resistance.
• Can be mixed with other materials.
Sport goods, aeronautic and space materials, automotive materials, wind generator blades. 3400 1.4 1.80
Cotton
• Natural cellulosic fiber.
•Good abrasion resistance.
• Good adhesion to rubber compounds.
• Excellent resistance to alkalisbut degrades in hot acids
Industrial products, latex glove, lining, printing blankets, filler/strengthening agent for rubber compounds, colorant fibers for paper and plastic, construction joint tapes, flocking and medical.
230 8 1.54
Fiberglass
• High tensile strength, excellent resistance to heat, and flame resistance.
• Electric-insulating,
• Doesn't absorp water and is resistant to acid and other chemical agents.
Insulators and heat-insulating materials, washing machines, refrigerators, reinforced plastic, building materials, etc.

Polyamide
• Strong synthetic fibre, elastic and abrasion resistant.
• Does not absorb water, resist stains.
• Absorbs oil and grease.
•Melts at high temperatures.
Tire cord, hoses, conveyer and seat belts, parachutes, racket strings, ropes and nets, sleeping bags, tarpaulins, tents, gaskets and seals.

Polyester
• The most important synthetic fiber, strong, resistant to stretching, shrinking, abrasion and most chemicals.
• Do not absorb water, but absorbs oil and grease.
• Melts at high temperatures.
Hoses, power belting, ropes and nets, thread, tire cord, auto upholstery, sails, floppy disk liners, and fiberfill for various products including furniture and high performance outdoor wear.
1100 13 1.38
Rayon
• The fiber is sold as artificial silk, highly absorbent.
• A disadvantage is that is loses its strength when wet
• Poor resistance to abrasion, expensive, and stretches and shrinks more than cotton.
Industrial products, hoses, medical surgical products, nonwoven products, tire cord.

Silk
• Natural fiber, created by the silk worm.
• Thinnest of all natural fibers, fair abrasion resistance, poor resistance to sunlight.
Gaskets and seals, mostly used in apparel and home fashion.

Steel
•High tenacity and low elongation at break.
• Electrical conductive and thermal resistant. 
Industrial products, tire cord and hoses, conveyor belts.
