Nowadays, all new energy vehicles need to use batteries, and the battery casing plays the role of protector. Today’s modified plastics editorial will come together with you to get to know the lead-acid battery casing flame retardant ABS material.
The most obvious feature of the lead-acid battery is its top plastic seal cover that can be unscrewed, with ventilation holes on it. So what material is used for lead-acid battery shells?
It is understood that the general lead-acid battery shell is commonly used ABS, PP, PE and other materials, while the high-grade valve-controlled sealed battery is generally used ABS, non-valve-controlled battery is generally used PP, PE and so on. The shell of lead-acid battery is mainly used to hold the electrolyte and pole plate group, the shell should be acid-resistant, heat-resistant, shock-resistant, and previously made of hard rubber.
Flame-retardant ABS material for lead-acid batteries
Flame-retardant ABS material is a special material for lead-acid battery shells. It has.
① High efficiency of flame retardant, which can give the composite material good self-extinguishability or incombustibility and meet UL94 standard.
②Good heat resistance, not easy to bulge under high temperature when injection molding into the shell.
③Good fluidity, not easy to appear silver lines or air marks in injection moulding, good dimensional stability and good air tightness.
④Good impact resistance, low temperature environment by the impact does not crack.
⑤ Special design of the formula, good heat seal and glue seal effect.
⑥The material does not contain cadmium, chromium and other harmful toxic heavy metals, the production and application process will not cause any pollution to the environment, in line with ROHS certification requirements.
