Needled mat is a new type of environmentally friendly material that is made of glass fiber, and after special production process and surface treatment, it forms a new type of environmentally friendly material that has good abrasion resistance, high temperature resistance, corrosion resistance, insulation, sound insulation and other characteristics. It can also be called needle-punched cotton, needle-punched cloth, needle-punched fabric and so on. This material has reasonable structure, better performance, high porosity, low gas filtration resistance, high filtration wind speed, high dust removal efficiency, and at the same time, it has the characteristics of bending resistance, abrasion resistance, and dimensional stability. Needled felts are mainly used as reinforcing substrates for the manufacture of thermoplastic sheet molding compound AZDEL and polypropylene sheet (GMT).
There are many types of needle mats, and the following are some common classifications:
According to the different materials, there are polyester needle mat, polypropylene needle felt, nylon needle felt and so on.
According to different working temperatures, there are ordinary polyester needle felt bags, acrylic needle felt bags, PPS needle felt bags, PTFE needle mat bags and so on.
These different types of needle felts have different characteristics and uses, such as polyester needle felts and polypropylene needle felts are wear-resistant and corrosion-resistant; while PPS needle felts and PTFE needle mats are suitable for filtration in high temperature and acid-alkali environments.
According to the specific working conditions and filtration requirements, you can choose the suitable needle mat material and model to get better filtration effect and service life.
