BX IM 227 Impact Modifier


BX IM 227 is a high-impact, burst-proof resin reinforcing agent with excellent compatibility with resin systems. It is recommended to be used in PC-related product systems with high impact strength, high elongation, screw cracking, and chemical resistance.

BX IM 227 is Equal to Dow EXL-2616, Kenaka M722, Send an inquiry to check the comparison test.


1. It has good impact resistance in PC systems;
2. In PC products, it has an excellent elongation at break, and the products have better explosion-proof performance and anti-beat performance;
3. It has good chemical resistance and can be applied to systems such as spraying and soaking solvents;
4. Structural features: hydroxyl silicon-modified methacrylic acid-butadiene-styrene.


BX IM 227 is recommended for PC, PC/ABS, and other resins, adding BX IM 227 to mix and granulate (suitable temperature: 240-300°C), or directly mix and inject, to obtain high-impact, impact-resistant products. The product is also suitable for PC/ABS, PC+GF, PC/PBT, and PC/PET systems.
Recommended dosage: 1-3%

The picture above is PC+10%GF, soaked in glacial acetic acid for 10 minutes, no cracking.

Results Analysis:

1. BX IM 227 has an excellent elongation at break and notched impact performance in PC applications. Materials using BX IM 227 have excellent performance in impact resistance, drop test, ball drop test, stress cracking test, and random artificial detection. Good anti-burst performance.
2. Immersion CCL4 test:
Carbon tetrachloride is a very strong non-polar solvent, which can dissolve most polycarbonate that has not been treated with chemical resistance. After soaking for a short time, most of its properties will be lost, or even completely burst. The polycarbonate added with BX IM 227 not only maintains the integrity of the spline but also maintains most of the physical properties of polycarbonate.
