Clearstrength^® 859 Impact Modifier

Clearstrength^® 859 is a high-efficiency MBS opaque impact modifier intended for use in injection molding and opaque sheet and profile applications. Clearstrength^® 859 imparts the highest impact strength in the Clearstrength^® impact modifier product line. Our patented manufacturing process ensures that Clearstrength^® 859 exhibits excellent lot-to-lot consistency which guarantees a high quality impact modifier that contributes to the uniformity of PVC compounds. 

Clearstrength^® 320 Impact Modifier

Clearstrength^® 320 is an MBS impact modifier designed for use in clear packaging and profile applications where quick fusion, and added impact strength is desirable. Our patented manufacturing process ensures that Clearstrength^® 320 excellent lot to lot consistency, uniform color hold, high impact strength and low gel levels. Clearstrength^® 320 is formulated to provide optimum clarity to film and sheet. 

Clearstrength^® E-920 and E-922 Impact Modifier

Clearstrength^® E-920 is a general-purpose methacrylate-butadiene-styrene (MBS) core-shell impact modifier designed to impart excellent ambient and cold temperature toughness to engineering polymers. Clearstrength^® E-920 impact modifier is recommended for use in polycarbonate (PC), polybutylene terephthalate (PBT) and polycarbonate blends (e.g., PC/PBT, PC/ABS) where superior low temperature impact performance and excellent colorability are required. Clearstrength^® E-920 is targeted for use in painted automotive applications, electrical/electronic components, appliances, business machines, lawn & garden equipment, and recreational vehicles where thermal stability, excellent low temperature impact and a good balance of physical properties are important. Clearstrength^® E-920 is offered commercially in both powder (E-920) and pellet (E-922) forms to provide ease of handling in your processes.

Clearstrength^® 303H Impact Modifier

Clearstrength^® 303H is an MBS impact modifier designed for use in clear packaging and profile applications where quick fusion, added impact strength and blue fluorescence is desirable. Our patented manufacturing process ensures that Clearstrength^® 303H impact modifier exhibits excellent lot to lot consistency, uniform color hold, high impact strength and low gels levels.

Clearstrength^® 223 Impact Modifier

Clearstrength^® 223 is an MBS impact modifier that is intended for use in injection molding and opaque sheet and profile applications. Our patented manufacturing process ensures that Clearstrength^® 223 impact modifier exhibits excellent lot to lot consistency which guarantees a high quality impact modifier that contributes to the uniformity of PVC compounds.

Clearstrength^® W300 Impact Modifier

Clearstrength^® W300 is an acrylic impact modifier which improves impact strength of PVC resin without impairing clarity. With its unique performance in clarity, weatherability, and impact strength, Clearstrength^® W300 has been used for many years in outdoor applications, such as corrugated sheets, sign boards, building materials and sheets and films.
