Anisotropy is caused when the polymer chains orient in the direction of flow, which leads to higher physical properties in the flow direction.

• The more polymer on the substrate surface, the better the adhesion. • Ensure that the chosen TPE is designed to bond to the substrate. • Appropriate TPE thickness — too thin can lead to delamination. • Use of mechanical interlocks in the component design. • Proper shut-off design. • Adequate venting is critical, especially at ends of flow. • Type of color concentrate carrier used in both the plastic and the TPE. • Pre-drying of the TPE overmold material, if required. • Substrate preparation and cleanliness. • Higher TPE melt temperature generally provides higher bond strength. • Control melt temperature by injection speed, 1st stage pressure, then barrel temps (to fine-tune). 2322 TPE Injection Molding Troubleshooting Problem: Beach marks and uneven shine Possible Cause High molecular weight formulations in highly polished mold. Additional Factors that Affect Adhesion • Grade of plastic substrate (glass-filled, mineral-filled, heat-stabilized, lubricated). • The more polymer on the substrate surface, the better the adhesion. • Ensure that the chosen TPE is designed to bond to the substrate. • Appropriate TPE thickness — too thin can lead to delamination. • Use of mechanical interlocks in the component design. • Proper shut-off design. • Adequate venting is critical, especially at ends of flow. • Type of color concentrate carrier used in both the plastic and the TPE. • Pre-drying of the TPE overmold material, if required. • Substrate preparation and cleanliness. • Higher TPE melt temperature generally provides higher bond strength. • Control melt temperature by injection speed, 1st stage pressure, then barrel temps (to fine-tune). 2524 Problem: Jetting Possible Cause High viscosity flow.

Our mission is to become the world’s premier provider of specialized polymer materials, services and solutions, as we execute our proven four-pillar strategy of Specialization, Globalization, Commercial Excellence and Operational Excellence. Lin also serves as a director for two other public companies and one privately-held biomedical polymer company, which provides her with additional experience she utilizes while serving as a valued member of our Board. �� Current Directorships: WESCO International, Inc.; American Electric Power Company, Inc.; and Interface Biologics Inc. Nominees for election to the Board are selected on the basis of the following criteria: Business or professional experience; Knowledge and skill in certain specialty areas such as accounting and finance, international markets, physical sciences and technology or the polymer or chemical industry; Personal characteristics such as ethical standards, integrity, judgment, leadership and the ability to devote sufficient time to our affairs; Substantial accomplishments with demonstrated leadership capabilities; Freedom from outside interests that conflict with our best interests; The diversity of backgrounds and experience each member will bring to the Board; and Our needs from time to time.
