MATERIALS SELECTION

POLYCARBONATE (PC) Light Diffuser

> High shock resistance (nearly unbreakable).

> Good light transmission.

> Flammability rating UL94 "HB" to "V0" (depending on material type).

> High heat deflection temperature (up to ca. 130 °C).

> Available in transparent and opal colours.

> UV-stabilized polycarbonate.

> Self-extinguishing according to CE regulations, polycarbonate tubes do         not allow the flame to spread.

 

POLY METHYL METHACRYLATE (PMMA) light diffuser

> Unmatched weather and aging-resistance (no yellowness-effect from UV-radiation).

> Very high light transmission.

> Flammability rating UL 94 "HB" (burns with very low smoke- and pollutant-level).

> Reasonably shock resistant.

> Heat deflection temperature from 850 °C to 1000 °C (depending on material type).

> Available in transparent, opal, diffuse/satin (frost) and individual colours.

> On request, application of specific material types, the shock resistance for certain needs (i.e. vandalism) can be improved.

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

 

TCP (THERMAL CONDUCTIVE POLYMERS)

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.

Using the colour measuring system, we produce custom colour stripes as per the colour requirement.
