PMMA阻燃材料

产品细节

聚甲基丙烯酸甲酯阻燃材料

耐候性

聚甲基丙烯酸甲酯具有优异的耐大气老化性。样品经过4年的自然老化试验，重量变化、抗拉强度、透光率

略有下降，颜色略有变黄，抗银纹性显著降低，冲击强度略有提高，其他物理性能基本不变

可燃性

聚甲基丙烯酸甲酯易于燃烧，其极限氧指数仅为

17.3，遗憾的是，它不能用于许多需要阻燃的地方

然而，PMMA的阻燃性并不容易，因为PMMA主要用于透明领域。要保持透明度，符合防火要求

这样的阻燃剂很少！（不透明阻燃剂相对简单，所以我在这里不再重复）。国内外可用的阻燃剂可能有：Sandofle 5060、

溴磷酸盐CBP、甲基膦酸二甲酯DMMP、四溴苯二甲酸二乙酯TBPH等。然而，这些阻燃剂也很难达到UL94V0水平，添加量往往超过30%甚至40%，这就是为什么市场上几乎没有目光

PMMA Flame Retardant Material

Product Details

PMMA flame retardant material

Weather resistance

Polymethyl methacrylate has excellent resistance to atmospheric aging. The sample has undergone 4 years of natural aging test, weight change, tensile strength, light transmission

The rate is slightly decreased, the color is slightly yellowed, the crazing resistance is significantly decreased, the impact strength is slightly improved, and other physical properties are almost unchanged.

Flammability

Polymethyl methacrylate is easy to burn, and its limited oxygen index is only.

17.3, It is a pity that it cannot be used in many places where flame retardancy is required.

However, the flame retardancy of PMMA is not easy, because PMMA is mostly used in the field of transparency. It is necessary to maintain transparency and meet the requirements of fire prevention.

There are few such flame retardants! (Non-transparent flame retardant is relatively simple, so I won’t repeat it here). The flame retardants available at home and abroad are probably: Sandoflame 5060,

Bromophosphate CBP, dimethyl methylphosphonate DMMP, diethylhexyl tetrabromophthalate TBPH, etc. However, these flame retardant

It is also quite difficult for the agent to reach the UL94V0 level, and the addition amount often reaches more than 30% or even 40%, which is why there are few sights on the market.
