Helps reduce noise in car interiors, SABIC's PC/ABS reduces friction of parts and is PTFE-free

For electric vehicles and hybrid vehicles, due to the use of battery power systems, there is less source noise from the power system than traditional gasoline vehicles
.

Therefore, reducing abnormal noise in the cab is critical for electric and hybrid vehicles
.
Saudi Basic Industries Corporation (SABIC) has introduced an unfilled, colorable, PTFE-free polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) that reduces rattles in automotive interiors

Reduce friction and stick-slip between molded parts

According to reports, the material's internally lubricated LNP Lubriloy N2000 is a paintable insert material that can significantly reduce friction and stick-slip between molded parts to limit or prevent unwanted noise
.
Proprietary compatible olefin alloys are free of silicone and polytetrafluoroethylene (PTFE)
.

Ed Williams, senior product manager at LNP Compounds, said: "A quiet, smooth ride is a hallmark of automotive quality and luxury, but since electric and hybrid powertrains have no source noise, cabin sounds may be more pronounced
.
"

He says the new LNP Lubriloy N2000 compound is very effective in limiting hum, squeak, rattle, and eliminates the need for secondary processing applications such as felt or tape
.
"This latest material innovation helps automakers provide consumers with a more enjoyable driving experience
," added Ed Williams

For consumer electronics applications requiring reduced friction or improved wear

SABIC's lubrication technology is based on fully compatible olefin alloy materials
.
It enables LNP Lubriloy N2000 compound to provide low coefficient of friction (COF) and excellent wear resistance for plastic parts moving on metal and plastic surfaces
.
When assessed using BSR test VDA 230-206, Lubriloy N2000 compounds have a Risk Priority Number (RPN) of less than 3, while unmodified PC/ABS materials typically have a Risk Priority Number of greater than 5
.

As mirror housings and trim, cup holders, button rails and heating, ventilation and air conditioning (HVAC) frames - this new material has the potential to be used in consumer electronics applications that require reduced friction or improved wear

Avoid PTFE, no trace impurities of PFOA

In July 2020, the European Commission restricted the content of perfluorooctanoic acid (PFOA), its salts and PFOA-related substances that may be present in materials
.
This industrial surfactant is commonly used in the production of PTFE
.
Suppliers must now demonstrate that PTFE-containing materials are below the recommended PFOA threshold (<25 ppb)
.

Using the LNP Lubriloy N2000 compound, manufacturers can now simulate the tribological properties of traditional lubricating materials while avoiding the use of PTFE and therefore any trace impurities from PFOA that may be present in PTFE
.

Customizable colors

To help designers create attractive automotive interiors, the new LNP compounds offer custom shades of in-mold color that are difficult to achieve with other commercially available compounds using solid lubricant packages such as graphite or molybdenum
.
Paintability is an additional feature of LNP Lubriloy N2000 compounds that addresses challenges often encountered with traditional silicone materials, as silicone oils can cause surface defects
.

To further assist automotive designers, SABIC is also developing next-generation lubricated LNP materials in stylish deep gloss black
