The advantages of transparent acrylic impact modifier can be summarized as: "More durable transparency and more stable quality." This is the fundamental reason why acrylic impact modifier replaces MBS impact modifier in outdoor or light-resistant transparent products.

Acrylic impact modifier has a saturated chemical structure and does not contain carbon-carbon double bonds, making it very stable against ultraviolet light and less prone to photo-oxidation.

MBS impact modifier, on the other hand, has a core butadiene rubber phase containing a large number of carbon-carbon double bonds, making it highly susceptible to UV attack and degradation.

Acrylic impact modifier can maintain the colorless and transparent appearance of products for a long time, without yellowing or fogging, and its mechanical properties are stable.

MBS impact modifier has excellent transparency initially, but it yellows rapidly in a short period, its transparency decreases, and its impact strength also decreases due to aging.

Therefore, any transparent product that needs to be exposed to light (especially outdoor ultraviolet light), such as skylights, outdoor billboards, face shields, and greenhouse panels, must use acrylic impact modifier.

Furthermore, although both have high initial transparency, acrylic impact modifier provides more durable protection.

Acrylic impact modifier's refractive index is a perfect match for PVC, achieving extremely low haze and extremely high light transmittance. Due to its resistance to yellowing, this superior optical performance lasts throughout the product's entire lifespan.

While MBS impact modifier initially offers comparable transparency and haze to acrylic impact modifier, its inherent poor UV resistance means this superior transparency is only temporary.

Therefore, for transparent products seeking a high-end, long-lasting appearance, acrylic impact modifier is key to ensuring the product always looks new.

Thus, unless your product is an absolutely low-cost, disposable, and completely light-blocking indoor item, transparent acrylic impact modifier is undoubtedly a far superior and more reliable choice than MBS impact modifier in transparent applications.
