DP-Poly S Deproteinized natural rubber Akrochem Rubber - Natural rubber, NR SEALANT ADHESIVE DP-Poly is a highly purified deproteinized natural rubber from which most of the proteins and ash have been removed. The purification of natural rubber produces a polymer with special attributes, i.e. hydrocarbon content of 96% compared to 93% of normal natural rubber, that have been found to be advantageous in many industries and applications. DP-Poly purified natural rubbers have higher hydrocarbon content and lower dirt, ash, nitrogen and volatile matter compared to traditional natural rubbers (NR), which leads to its many interesting and beneficial characteristics. DPPoly CV is used in high quality natural rubber articles. Listed below are some of the benefits of utilizing DP-Poly NR versus normal NR and their corresponding applications: lower rate of creep/stress relaxation : motor and building mounts, seals, bearings, shock absorbers, etc. lower water absorption : electrical insulation, marine parts, stator pumps, tank linings, etc. more transparent/easier to color : molding and extruding clean tubings, hoses, toys, etc. lower protein, antigen content : pharmaceutical adhesives, teats, diapers, stoppers, syringes, etc. Highly purified deproteinized natural rubber. Can be used in high quality natural rubber articles. Possesses low rate of creep/stress relaxation, low water absorption and good transparency (easy to color).
