The single ply roof membrane industry uses various rubber-based adhesives to bond the seams at which adjacent rolls of membrane overlap. Since such roofs frequently carry 20-year warranties, maximizing adhesion is always desirable. The adhesion problem is exacerbated in that the membranes used are based on highly... 

Applications of ethylene-propylene copolymers and terpolymers include automotive (the major use area), thermoplastic olefin elastomers, single-ply roofing, viscosity index improvers for lube oils, wire and cable insulation, hose, appliance parts, and polymer modification.

A shift toward single-ply roofing as compared to built-up roof systems has an important influence on the type of foam being utilized. Thus the lower cost of expanded PS has promoted its use in preference to PU foam and extruded PS in single-ply applications. This is facilitated by the fact that the problems of damage to expanded PS foam from hot pitch when used in built-up roof systems are not encountered in single-ply systems.

In 1996, single ply roofs (SPRs) accounted for approximately 37% of new commercial roofs and 31% of renovated commercial roofs (National Roofing... 

For flexible sheeting, as single ply roofing use, PVC and ethylene-propylene-diene monomer (EPDM) are expected to be the main polymers used. For wall and floor coverings PVC is still expected to continue to dominate the construction market. PVC will be the main plastic used for pipe and conduit, wire and cable, profiles and flooring applications, while EPS will be mostly used in insulation. 

Vector SBS, SIS, and SB styrenic block copolymers are produced as diblock-free and diblock copolymers. The company s process to make linear SBCs yields virtually no diblock residuals. Residual styrene butadiene and styrene isoprene require endblocks at both ends of the polymer to have a load-bearing segment in the elastomeric network. However, diblocks are blended into the copolymer for certain apphcations. Vector SBCs are injection molded, extruded, and formulated into pressure-sensitive adhesives for tapes and labels, hot-melt product-assembly adhesives, construction adhesives, mastics, sealants, and asphalt modifiers. The asphalts are used to make membranes for single-ply roofing and waterproofing systems, binders for pavement construction and repair, and...

General-purpose elastomers represent the work horse rubbers of the rubber industry. They are the lowest cost, most cost-effective rubber polymers available today. The vast majority of these raw elastomers are used in the tire sector however, a large amount is also used in nontire applications as well, such as single-ply roofing, hose, dynamic parts (such as bushings, isolators, and dampers), and conveyor belts. 

EPDM is the fourth highest volume general purpose elastomer used today in the ruhher industry. At 2.7 hillion pounds of global annual production in 2010, EPDM represents about 10% of the total synthetic rubber production. However, unlike NR, SBR, and BR, this synthetic rubber is mostly used in the nontire sector (only a small amount of EPDM may be used in tire white sidewall compound, cover strip, and bicycle tires). EPDM is commonly used in single-ply roofing, in automotive weatherstrips, and hundreds of other applications. 

Therefore, EPDM is commonly preferred for making single-ply roofing. It is also the rubber of choice for the exterior weatherstripping for automobiles. 

CSM compounds possess excellent resistance to ozone attack, oxidation, and weathering, even for nonblack products. Also, these CSM compounds usually possess some oil, water, and chemical resistance. Therefore, CSM compounds are used in environmental applications (especially pond linings), insulation for cables, spark plug boots, coated fabrics, hose covers, single-ply roofing, rafts, and folding kayaks.
