Speedboat ship type D anti-collision strip
D-type anti-collision strips for speedboats use EPDM, a terpolymer of ethylene, propylene and non-conjugated diene. Diolefins have a special structure, and only one of the two bonds can be copolymerized, and the unsaturated double bond is primarily used as a cross-chain. The other one that is not full will not become the main polymer chain, but will only become the side chain. The primary polymer chain of EPDM is completely full. This feature makes EPDM resistant to heat, light, oxygen, and especially ozone. EPDM is essentially non-polar, resistant to polar solutions and chemicals, has low water absorption, and has outstanding insulating properties.
