How To Identify The Quality of Flame Retardant PP Sheet

Flame-retardant PP sheet is a plastic sheet made of PP resin, with various functional additives added through extrusion, calendering, cooling, cutting and other processes. Flame retardant PP sheet is a semi-crystalline material. It is harder than PE and has a higher melting point. Because the homopolymer PP temperature is very brittle above 0C, many commercial PP materials are random copolymers with 1-4% ethylene content or block copolymers with higher ethylene content. Copolymer PP materials have a low heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but have strong impact strength. So, how to identify the quality of flame retardant PP sheet?


1. Check its surface gloss. The poor gloss is recycled plastic.


2. Observe its toughness. The pure raw material flame retardant PP sheet has excellent toughness and can be slightly bent.


3. Check the cutting surface. After cutting recycled plastic, there will be a variety of debris in different colors.


4. Check its density. The density of PP polypropylene is 0.92~0.93. All materials floating on the water are polypropylene.


5. The flame retardant PP sheet is heated and welded. Smoke comes out when welding recycled plastic.


6. Light transmittance, recycled plastics have poor light transmittance.


7. Toughness, recycled plastic is also much worse.


8. Flame-retardant PP sheet density, throw it into the water to see if it floats on the water, most of the recycled water sinks to the bottom.
