Polypropylene is autoclavable and polyethylene is not. Polypropylene can withstand high temperatures (it's melting point is 130°C), but is less suitable for freezing temperatures where it can become brittle. The melting point for polyethylene is 115–135 °C and it is best for option freezing temperatures.
10/4/2019 · Other plastics such as PET, PP, HDPE, PA12, PA11, PA6, PES, PPO, PBT and PPO are regarded as fair. Note that a PC/ABS alloy is also graded as fair. Good resistance to ultraviolet rays can be achieved from polymers extruded by Zeus such as PTFE

PP is the main raw material of melt blown cloth, and the fiber diameter can reach 1-5 μ M. There are many gaps, fluffy structure and good anti wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption.

The pore size of a filter cartridge is measured in microns. The smaller the micron rating, the finer the particulate removed. Which size micron filter you need depends on the size of the smallest particle that needs filtering from your water. A 5-micron filter, for example, removes particles as small as 5 microns.
