Nylon-rubber laminates

Linear polyesters Polyesters may be obtained in a wide variety of forms including rubbers, fibres, films, laminating resins, surface coatings and thermoplastic moulding powders. The last named are somewhat similar to the nylons but are more rigid. Chemical applications, would appear to be limited because of their sensitivity to alkaline solutions and hot water. 

They are fabricated from a variety of inorganic, organic, and naturally occurring materials and generally contain pores that are greater than 50—100 A in diameter. Materials such as nonwoven fibers (e.g. nylon, cotton, polyesters, glass), polymer films (e.g. polyethylene (PE), polypropylene (PP), poly(tetrafluo-roethylene) (PTFE), poly (vinyl chloride) (PVC)), and naturally occurring substances (e.g. rubber, asbestos, wood) have been used for microporous separators in batteries that operate at ambient and low temperatures (<100 °C). The microporous polyolefins (PP, PE, or laminates of PP and PE) are widely used in lithium based nonaqueous batteries (section 6.1), and filled polyethylene separators in lead-acid batteries (section 7.3), respectively. 

If the RP product requires flexibility, the choice is limited to plastics such as EVA, ionomer, polyethylene, vinyl, polypropylene, fluorocarbon, silicone, polyurethane, plastisols, acetal, nylon, natural rubber, or some of the rigid plastics that have limited flexibility in thin sections e.g., thin laminations are quite flexible. 

These calculations have been thoroughly tested and agree closely with experiment. The circles and squares are the experimental points and the lines are the theoretical predictions for a nylon fiber reinforced rubber. The angle ply laminate is predicted from the ply properties. The... 

Table 8.2 demonstrates the degree of adhesion obtainable between laminates of square woven fabrics when various rubbers are bonded to rayon, nylon and cotton.
