Thermoplastic Elastomers, or Thermoplastic Rubber compounds, as they're sometimes called, are a class of materials that behave a lot like rubber, but process like plastic. TPEs consist of hard and soft phase systems in the form of blends, alloys, or copolymers.
Modified bituminous roof membranes continue to be popular option for low-sloped roofs due to their proven performance. Historically these products have been torch-applied, mop-applied using hot asphalt (SBS only), or applied with solvent-based adhesives.
Pressure sensitive adhesive (PSA) tape offers manufacturers in many markets a range of benefits. These include:Improved product durability;Reduced product weight;Lower production costs;Enhanced product aesthetics;Increased productivity.
Bitumen is a form of waterproofing and road building material that has been utilized in some form since ancient times. Despite an estimated 102 million tonnes of bitumen being used globally, the bitumen used in waterproofing is largely split between two types of ‘modified bitumen’: elastomeric SBS and plastomer APP.
Pressure-sensitive adhesives are divided into categories based on the chemical composition of the adhesive: Rubber-based and acrylic adhesives. The chemical makeup of the product is a major contributor to the performance of the product.
The Global Styrene Ethylene Butylene Styrene (SEBS) Market is expected to register an estimated CAGR of 3.91% over the forecast period 2018-2023. The major factors driving the growth of the market is rising demand from the adhesive & sealant industry.
one use for modified asphalt in roofing applications is in waterproofing underlayment. An underlayment is a layer of material placed between the roof deck and the exterior surfacing material (typically shingles, wood shake, metal, tile, slate or cap sheet). It is a critical, though often overlooked, component of any complete roofing system.
Overmolding is the injection molding process where one material (usually a TPE) is molded onto a second material (typically a rigid plastic). If properly selected, the overmolded TPE will form a strong bond with the plastic that is maintained in the end-use environment.
Elastic part industry usually said TPE is SEBS modified by the composite functional materials. TPE elastomer with excellent overall performance, is the soft material applied mostly during over molding production , two-color injection.
