Do Flame Retardant Nonwovens Always Block the Net? Here Comes the Savior!

Spunbond nonwoven fabrics are not only used in the Eisai market and package market, but also in the home textile market, such as sofa wrap, household appliance cover, mattress, etc. However, the raw material of nonwoven fabrics, polypropylene, has the characteristics of being flammable in open flame and high temperature, and contact with oxidizer will cause the danger of combustion, so the fire regulations formulated by the Ministry of Public Security of China have put forward flame retardant requirements for such products, and then flame retardant nonwoven fabrics have come into everyone's view.

Flame retardant nonwoven fabric is a new generation of environmental protection material, heat resistance and anti-aging cycle are better than ordinary nonwoven fabric, can be added in the production process of flame retardant masterbatch and later in the surface coated with flame retardant to achieve flame retardant effect.

Flame Retardant Masterbatch

Compared with flame retardants, flame retardant masterbatches have better performance in storage and processing. Longquan Hongye has developed many kinds of flame retardant masterbatches, such as HY-F08W, HY-F820, HY-F822, HY-F828 and HY-F2810, in response to the requirements of different customers for flame retardant performance.

The dispersibility of HY-F829 has been greatly improved compared with the previous flame retardant masterbatches, which effectively solves the problem that the flame retardant masterbatches are easy to block the web during use, and has little effect on the color of the nonwoven fabric. It can pass the British Standard with only 1.5%-3.0% addition (typical application), and has good flame retardant effect and low halogen environmental protection, which meets the EU RoHS environmental requirements.

Tips for Use

Some customers will add a large amount of calcium carbonate filler in the production, calcium carbonate in the combustion of heat expansion and produce countless microscopic pores, increasing the combustible area in contact with oxygen, promote the burning speed, so that the flame retardant effect is greatly reduced, for products with flame retardant requirements should be used as little as possible or no calcium carbonate, or increase the amount of flame retardant masterbatch use, the specific amount of use needs to be adjusted by customers according to their own formulations. The specific amount of use needs to be adjusted by the customer according to his own formula.

In order to achieve the best effect, customers need to consider the flame retardant requirements, test conditions and substrates in the process of use to determine.
