Compatibility of Resorcinol–Formaldehyde Resin with Polyester Cord

Abstract

Cord used in the carcass of high-speed car tyres must possess a high modulus, fatigue strength, and low shrinkage. These requirements are satisfi ed by polyester cord, which has a considerably higher modulus, lower shrinkage, and a satisfactory fatigue strength, albeit lower than in the case of nylon-66 cord. Therefore, in recent years, the consumption of polyester cord has increased continually both abroad [1] and in Russia.

A new approach with prepregs for reinforcing nitrile rubber with phenolic and benzoxazine resins

“…15 The reinforcement of synthetic polymers such as cardinol-formaldehyde, ultra high molecular weight polyethylene (UHMWPE), polyaniline, resorcinol-formaldehyde and epoxy resins in various rubbers has been studied to improve the mechanical properties. [16][17][18][19][20][21][22] The reinforcement of phenolic resins with chloroprene, ethylene propylene diene monomer (EPDM) and NBR, and epoxy resin with SBR through in situ polymerisation has also been discussed. [23][24][25] The resin reinforcements for NBR are prepared by most common methods such as in situ polymerization, solution, melt mixing, blending, coating and latex blending.…”
