汽车罩用Pmma颗粒

产品详细信息

通常用于汽车罩，

汽车罩用PMMA树脂

紫外线：石英可以完全透射紫外线，但价格很高。普通玻璃只能通过0.6%的紫外线。PMMA颗粒能有效滤除波长小于300nm的紫外线。与聚碳酸酯相比，PMMA在紫外光下具有更好的稳定性

红外：PMMA颗粒允许小于2800 nm的红外（IR）波长通过。当波长小于25000nm时，长波红外可以被基本阻断。有一种特殊颜色的PMMA塑料，允许特定波长的红外通过，同时阻挡可见光（用于远程控制或热感应等）

应用：

1。标牌、显示器和建筑材料用挤压板材<跨度>2。尾灯、仪表盖和遮阳板等汽车零件3。餐具、厨房用具、礼品和浴室配件等一般杂物4。光学镜头，如太阳镜、阅读眼镜和照相机镜头<跨度>5。LCD显示屏的导光板<跨度>6。其他应用，如手机显示屏、时钟盖、灯罩/配件、光纤、玩具等

Pmma Granules For Car Cover

Product Details

The density of PMMA granules is lower than that of glass: the density of PMMA granules is about 1.15-1.19 g/cm3, which is half of glass (2.40-2.80 g/cm3) and 43% of metallic aluminum (belonging to light metal).

PMMA granules have higher mechanical strength: PMMA granules have higher strength and 7 to 18 times higher tensile and impact resistance than ordinary glass. Stretched PMMA plastic can be used as bulletproof glass and as a canopy on military aircraft.

The melting point of PMMA granules is lower: PMMA granules have a melting point of about 130–140 ° C (265–285 ° F), which is much lower than the temperature of about 1000 degrees of glass.

PMMAgranules have higher light transmittance

Visible light: PMMA granules is currently the most excellent polymer transparent material with a light transmittance of 92%, which is higher than that of glass.

Usually is used for car cover,

Ultraviolet light: Quartz can completely transmit ultraviolet light, but the price is high. Ordinary glass can only pass 0.6% of ultraviolet light. PMMA granules can effectively filter out ultraviolet light with a wavelength of less than 300nm. Compared with polycarbonate, PMMA has better stability under the condition of ultraviolet light.

Infrared: PMMA granules allow the passage of infrared (IR) wavelengths less than 2800 nm. Longer wavelength IR, when less than 25,000 nm, can be substantially blocked. There is a special colored PMMA plastic that allows specific wavelengths of IR to pass through while blocking visible light (for remote control or thermal sensing, etc.).

The glass transition temperature of PMMA granules is about 105 °C.

Application:

1.Extruded sheets for signage, displays and building material

2.Automotive parts such as tail lamps, meter covers and sun visors

3.General sundries such as tableware, kitchenware, giftware and bathroom accessories

4.Optical lenses such as sunglasses, reading glasses and camera lenses

5.Light guide panels for LCD displays

6.Other applications such as mobile phone display panels, clock covers, lighting covers/accessories, optical fibres, toys, etc
