MBS Impact Modifiers in Polycarbonate

MBS Impact Modifiers in Polycarbonate

Polycarbonate (PC) is known for its transparency, its excellent resistance to impact and its ability to withstand high temperatures during the lifespan of the final article.

However, PC's low chemical resistance (gasoline) is an issue for automotive applications. The injection molding of high viscosity grades is another limitation, especially when high impact resistance is required.

Moreover inherent performances of PC, such as impact, are also seriously compromised when colored pigments, fillers or Flame Retardant additives are used in the compound.

Recycled PC's are a cost-effective solution for compounders. However, the recycling steps reduce PC's mechanical performance, making the use of impact modifiers necessary in recycled PC, in order to reach the desired level of performance.

Benefits of MBS Impact Modifiers in Polycarbonate

Benefits	Description
Exceptional Low-temperature Impact Performance	MBS Impact modifiers allow PC and particularly high flow PC to achieve high impact performance at very low-temperatures. High-performance impact modifiers based on butadiene rubber (ABS or MBS) are detrimental to the inherent UV and heat stability performances of polycarbonate. In weatherable outdoor applications or high heat environments, it will be critical to use a very stable Impact Modifier that will still provide high impact performances. Impact modifiers are designed to respond to this technical challenge.
Excellent Weatherability & Heat Aging	MBS Impact modifiers provide excellent weatherability expected of an all-Acrylic Impact Modifier. This allows impact modifiers to be used in applications that demand good color hold and retention of mechanical properties upon typical outdoor exposure, yielding products that retain long-term performance under severe conditions.
Exceptional Mold-in Colorability	MBS Impact modifiers provide far more superior colorability than most of the acrylic modifiers available on the market, which are known to lower color intensity thus making dark color parts difficult if not impossible to achieve. Based on a patented technology, they have opened the door for applications that demand good color hold and unique mechanical properties retention upon exposure to the elements.
