Common types of fiberglass mats

1. Fiberglass Needle mat/Felt

Fiberglass Needle mat/Felt is widely used in carbon black, steel, non-ferrous metals, chemical industry, incineration and other industries. In China, industrial filter material is the main application field of glass fiber needle felt.

Glass fiber needled mat/felt is used for interior decoration, sound absorption, heat insulation, shock absorption, and flame retardancy. Roof and door gaskets, bonnet (adhered to the inside), engine and compartment partitions, trunk gaskets.

Using the heat preservation and heat insulation effects of the microporosity of the needled mat/felt, it can be used for heat preservation and heat insulation of various heating elements in pipelines. Using the filtering and sound-absorbing effects of needle mat/felt, it can be used in noise-reducing dust collectors for general gasoline engines of automobiles and motorcycles.

In addition, glass fiber needle mat/felt can also be used for geotextiles, insulating materials, etc.

2. Glass fiber continuous strand mat

The glass fiber continuous strand mat is made of continuous glass fiber strands as the main raw material. Compatible with oxygen, phenolic and polyurethane resins. Products can be used in resin transfer molding (RTM) vacuum forming and pultrusion processes, such as automotive headliners, insulating materials for transformers.

3. Glass fiber chopped strand mat

The glass fiber chopped strand mat is made of glass fiber chopped strands bonded by powder or emulsion binder. Chopped strand mat is mainly used to manufacture FRP products through hand lay-up process, winding process and molding process. Typical products include plumbing fixtures, plumbing, building materials, automobiles, furniture, cooling towers and other FRP products.

4. Glass fiber surface mat/felt

The glass fiber surface mat is mainly used for the surface layer of FRP products. The product itself has the characteristics of uniform fiber dispersion, soft texture, good fiber surface smoothness, low glue content, fast resin penetration and good moldability. The product can significantly improve the surface corrosion resistance, pressure resistance and leakage resistance of products, and has the advantages of long service life. In addition, the product is also suitable for injection, molding and other FRP forming techniques.

5. Fiberglass Roofing mat/Felt

RGM is a good base for making SBS, APP modified bitumen waterproofing membrane and colored bitumen fiberglass shingles, and is free from longitudinal reinforcement of the entire felt, which fully improves the longitudinal tensile strength and tear strength of the felt. Linoleum made of RM series felt as the base material can overcome the shortcomings of linoleum’s high temperature flow, low temperature embrittlement, easy aging, etc., so that the linoleum has excellent weather resistance, enhanced anti-leakage, and extended its service life, so it is used for roofing. Ideal substrate for materials such as linoleum. At the same time, RGM series felt can also be used as the backing material of house insulation.

6. Glass fiber stitched chopped strand mat

Stitch-bonded chopped strand mat is suitable for unsaturated polyester resin, vinyl resin, phenolic resin and epoxy resin. This product is widely used in pultrusion molding process, hand lay-up molding process and resin transfer molding compound process. The main end products are: FRP hulls, plates, extruded profiles and pipeline linings. The stitch-bonded chopped strand mat is a mat made of glass fiber untwisted roving that is chopped into a certain length and then laid uniformly without orientation, and then stitched with a coil structure.

7. Fiberglass stitched combo mat

Fiberglass stitched combo mat can be applied to unsaturated polyester resin, vinyl resin, phenolic resin and epoxy resin. This product is widely used in FRP pultrusion process, hand lay-up process and resin transfer molding compound process.

​​Fiberglass stitched combo mat is the most widely used in the shipbuilding industry. Fiberglass stitched combo mat is a glass fiber mat made of untwisted roving and a layer of chopped strands that are uniform and non-directional, and then stitched with a coil structure.

8. Glass fiber sandwich composite mat/felt

Sandwich composite felt is made of synthetic non-woven core material, front and back or single side with fiber chopped layer (without binder) or fiber cloth and multi-axial fabric after stitching. Products can be applied to resin transfer molding (RTM), vacuum bag molding, compression molding, injection molding and SRIM and other molding processes.

10. Glass fiber needle-punched composite felt

Needle-punched composite felt is a new type of glass fiber reinforced material in which chopped strands are uniformly distributed on the woven base fabric and are needle-punched. The product does not contain adhesive or other stitching threads, and has the characteristics of good mold filling and overmoldability, high three-dimensional strength, fast soaking, and easy debubbling. It is suitable for hand lay-up, pultrusion, winding, GMT, RTM, etc. Molding.

11. Air purification glass fiber fluffy filter mat/felt

The air purifying fiberglass fluffy filter felt is made of fiberglass in a fluffy state. Therefore, it has a large dust holding capacity and a long service life, and is an excellent material for primary air filtration.
