Polyvinyl chloride (PVC)

PVC extrusion profiles

Polyvinyl chloride, commonly abbreviated as PVC, is the third-most widely produced polymer after polyethylene and polypropylene. PVC is used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. PVCs that are relatively low cost, biological and chemically resistant with workability have resulted in them being used for a wide variety of applications. It being used for lighting fixture base and different applications in other industries, where cost or vulnerability to corrosion limits the use of metal.

CYCOLOY

Plastic extrusions for buses

CYCOLOY is the blend of polycarbonate/ acrylonitrile-butadiene-styrene (PC/ABS) high impact amorphous thermoplastic blends, combining ease of processing with low-temperature ductility. With excellent impact resistance, heat resistance, and outstanding aesthetics, CYCOLOY blends can be tailored to meet specific property requirements, to help balance performance, cost and process ability. CYCOLOY resin blends provide an excellent design solution when both appearance and durability are important.

TCP (Thermal conductive polymers)

Plastic extrusions for railway coaches

We are the pioneer in introducing Thermal conductive polymers for replacing metal heat sinks and housings in light-emitting diode (LED) luminaries. The new compounds have been specially formulated to increase the thermal management design options available for LED lighting as it expands into a broader range of end-use markets including automotive, industrial, retail, and consumer goods.

The thermoplastic compounds reduce weight by up to 50%, injection-molding processing simplifies and lowers manufacturing costs, inherent color eliminates the need for painting or secondary operations, and heat sink life is increased in wet environments due to plastics corrosion resistance.

As a customized solution provider, we have the ability to modify these thermally conductive polymers to meet the performance requirements of specific LED lighting applications.

ADVANTAGES OF USING SPECIALIZED POLYMERS

Improved-clarity polycarbonate resins provide an array of performance properties that help lights operate effectively over their full useful life with higher lumen outputs. Firstly, polycarbonate is renowned for outstanding impact resistance that surpasses the performance of PMMA by a factor of 10 in typical lab or practical impact measurements and that of glass by a factor of 30.

Improved-clarity polymers offer enhanced anti-yellowing performance to maintain light transmission and resist becoming brittle so they retain their excellent impact properties.

In outdoor applications, transparent and weather able polymers offer a welcome alternative to both glass and other brittle aletrnatives, because they combine high impact performance to protect the internal solid-state circuits from vandalism and other threats, meet stringent UL requirements for weather ability and flame retardant and optimize forward transmission of light. In contrast, breakable glass does not provide sufficient impact protection, and PMMA does not meet UL94 V0 requirements.

Improved-clarity polycarbonate can handle extended exposure to temperatures from 110°C to 130°C, while retaining their mechanical and optical properties.
