With the rapid development of the automobile industry, light weight, comfort, greenness and environmental protection have become the main development directions of the automobile industry. Automobile lightweight technology can reduce body weight and fuel consumption, which is one of the important measures to achieve energy saving and emission reduction.

At present, plastic materials are more used in auto parts to replace heavy and expensive metal components. “Replacing steel with plastic” has become the preferred solution to meet the development requirements of the automobile industry. The degree of plasticization of automobiles has become an important indicator to measure the level of automobile design and manufacturing. . Among them, modified plastics are the main force of automobile plasticization.

Modified plastics have excellent properties, and can be customized to develop special modified plastics according to the needs of automobile manufacturers to meet various needs of automobile manufacturing and use, and the LNP™ product series of Saudi Basic Industries Corporation (SABIC) Is one of the outstanding representatives.

As a pioneer in the research and development of chemical compounding technology, LNP series products were born in the 1940s and are the most important engineering thermoplastics brand under SABIC. It provides customers with value-added solutions based on a unique combination of resin systems, copolymers, fillers, additives and flame retardants with outstanding mechanical, optical, electrical and thermal properties and outstanding environmental friendliness.

Relying on its rich product portfolio and more than 70 years of service experience in the automotive industry, LNP compounds and copolymer resin products can provide automotive high-performance material solutions including interiors, exteriors, ADAS, lighting and fuel systems. solutions to help car manufacturers create cars that are lighter in weight, better in performance and more beautiful in appearance.

Car interiors include instrument panels, steering wheels, seats, control buttons, air conditioning outlets, shift heads, door trims, door handles, etc. All interior decorations. As the part that consumers are in direct contact with, the aesthetics, functionality and comfort of car interiors are crucial to the overall design and manufacture of the car, and there are high requirements for materials in terms of wear resistance and impact resistance. Various series of LNP modified materials and copolymer resins provide new ideas for different types of interior design and innovation.

● Application 1

● Application 2

LNP LUBRILOY ZL003 resin is a lubricating modified polyphenylene ether (PPE) containing 15% PTFE. It has better acid and alkali resistance than PC materials, as well as wear resistance and low friction coefficient. It can be used in central control Table slides and guides.

● Application 3

LNP™ LUBRICOMP™ NXCY620 resin is a lubricant modified PC/ABS alloy with low wear friction, good chemical resistance, no grease, low shrinkage, and can be applied to multimedia frames to make them more durable, dimensionally more precise Good and reduces friction noise and air pollution etc.

If the car interior is to provide people with a comfortable driving experience, then the car exterior is to make the vehicle more beautiful and to ensure the safety of the ride. Common car exteriors include front and rear bumpers, rearview mirrors, luggage racks, grilles, radiator trim covers, crash beams, anti-scratch strips, wipers, etc. Since the exterior is the part that is in direct contact with the external environment, there are high requirements for the weather resistance, heat resistance, appearance, color, etc. of the material.

LNP SLX copolymer resin is a spray-free material with excellent weather resistance, which can form a self-renewable anti-UV protective layer on the shallow surface (3-10um), so that the exterior of the material can be used for 10 years or even Longer time, still maintains good performance and appearance. At the same time, LNP SLX copolymer resin has its own coating-free high-brightness properties, and has good gloss, scratch and abrasion resistance, etc., adding a sense of fashion, luxury and quality to automotive exteriors.

On the other hand, in order to meet the personalized color and design requirements of automotive exteriors, LNP SLX copolymer resin provides rich base colors with high light transmittance, and has a variety of coloring spaces, helping automotive exteriors to achieve infinitely variable colors and colors. Exterior.

Automotive lighting systems include lights, ambient lights, etc., and are generally composed of reflectors, lenses, housings/light sources, electronic circuits, and installation accessories. As the “eye” of the car, the car lamp has high requirements for the heat resistance, heat conduction, wear resistance and light transmission performance of the material. In this regard, LNP modified materials and copolymer resins put forward their own “views”.

● Application 1

LNP XHT copolymer resin has excellent high temperature resistance with HDT up to 183°C. Compared with other high-temperature resistant PCs, it has higher performance after metal coating and better color stability, and can be used in automotive lighting trims, headlight inner lenses, reflectors, fog lamps, etc. The structure design can better prevent blistering and micro-cracking caused by high temperature, and effectively reduce the system cost.
