Chopped strands

We produce chopped glass fibre strands from two types of glass: E-glass with thermal resistance of up to 600°C and SiO2-glass with thermal resistance of up to 1000+°C. Each glass type has its own properties, hence also application areas.

Chopped strands are short glass fibre strands that retain the initial structure of the yarn also when chopped. The lenght of chopped strand is 3, 6, 9 to 12 mm, while the filament diameter is 6, 9, 11 to 13 μm.

Chopped strands
(E-Glass 600º C)

Chopped glass fibre strands which are made of alkali-free alumina borosilicate E type glass fibre (EC) have a lenght of 3, 6, 9 and 12 mm, while the filament diameter is 6, 9, 11 to 13 µm.

Application: chopped strands are designed for the production of glass paper and air filters for cars.

Type of sizing: SCG; SC; SP - silane sizings.

Parameters: chopped glass fibre strands are delivered in plastic bags, 20 and 25 kg per bag.

Designation: e.g. EC 6-6mm, where:
EC - type (chopped E-glass strand),
6 - filament diameter, μm,
6 mm - length of chopped fibre.

Chopped strands
(SiO2-Glass 1000º+C)

We offer chopped glass fibre strands with a high SiO2 content or silica chopped glass fibre strands (KC) with heat resistance up to 1000+°C. High-silica chopped strands are a new-generation heat resistant material.

Application: broad-spectrum; products can be used in various high-tech fields (such as aviation and space industry, chemical industry, metallurgy, special clothing manufacturing, power production, machine building, etc.) that require heat resistant (up to 1000+°C) materials. High-silica materials can be used anywhere where low thermal conductivity, inertness to most chemical reagents, resistance to organic and mineral acids (except hydrofluoric acids and phosphoric acids), weak alkali, water and high-pressure steam is required.

Shrinkage at 1000°C:

  • up to 12% for thermally non-treated fibre,
  • 1-3% for thermally treated (TA) fibre depending on the treatment mode.

Parameters: high-silica chopped glass fibre strands are delivered in plastic bags, 10 kg per bag.

Designation: e.g. KC6-6, where:
KC - type (high-silica chopped glass fibre strands),
6 - diameter of filament in μm,
6 - length of chopped fibre in mm.
