Diene™ is our quality polybutadiene rubber product.  The product has applications in plastics, tires and mechanical rubber goods.

Diene

Trilene® Liquid EPDM represents a class of specialty lower molecular weight EPDM polymers that are available in liquid or free-flow powder form.  Trilene® is used in gear oils and greases, caulks, adhesives, roof coatings and many other applications that require a low molecular weight liquid EPDM product having the characteristics of conventional EPDM. Trilene FreeFlow® products are free-flowing polymers made by combining Trilene® Liquid EPDM and silica.

Lion Elastomers Trilene

Stereon™ is Lion's polymerized styrene-butadiene di-block and tri-block copolymers. Our thermoplastic elastomers and versatile block copolymers can be useful in applications such as grafting and melt blending, as well as adhesives, roofing and paving asphalts.

Royalene® EPDM is used in a wide variety of elastomeric applications that require superior heat, ozone and chemical resistance, excellent long term aging and outstanding weathering. Royalene® applications include automotive, industrial and consumer hoses, weatherseals, molded goods, wire and cable insulations, window profiles, roof sheeting, thermoplastic elastomers, and viscosity modifiers for lubricants.

Royalene

Royaltherm® is a silicone-modified EPDM.  It is ideally suited for high-temperature applications.  Compared to normal EPDM, Royaltherm® provides better heat and weather resistance.  Compared to silicone, it provides better tensile strength, flex fatigue resistance and other mechanical properties.  It exhibits good electrical properties in moist conditions and, unlike silicone, retains physical properties even in hermetically sealed environments.

Royaltherm

Duradene™ SSBR is a solution polymerized styrene butadiene rubber. Our SSBR can be used in a variety of applications, including uses in tire compounds and extruded and molded rubber goods.

Duradene

RoyalEdge® EPDM is used in a wide variety of elastomeric applications that require superior heat, ozone and chemical resistance, excellent long term aging and outstanding weathering. RoyalEdge® EPDM products are terpolymers of ethylene, propylene and a non-conjugated diene (ENB or DCPD) that vary in viscosity, ethylene/propylene ratio, and type and amount of diene according to desired processability and end properties.
