The main products of pet polyester spunbond non-woven fabrics are polypropylene and polyester (long fiber, short fiber) non-woven fabrics. Our most common and commonly used applications are non-woven bags, non-woven packaging, etc.; for Spunbond non-woven fabrics are easier to identify because they generally have good two-way fastness. Generally, the nipping points of spunbond non-woven fabrics are diamond-shaped.
?pet polyester spunbond non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell the non-woven fabric. Chemical stability It also improves with the increase of crystallinity.
Suzhou New Material Technology Co., Ltd. is a manufacturer specializing in the research, development and production of polytetrafluoroethylene materials. After years of painstaking research and development, the company not only has strong research and development capabilities, complete testing methods and domestically advanced Experimental equipment has also attracted a large number of outstanding technical talents.
