Cray Valley is a leading manufacturer of low-molecular-weight, butadiene homopolymers and copolymers, hydrocarbon tackifying resins, metallic monomer salts, and specialty monomer products.
Marketed under the brand names Ricon®, Krasol®, Poly bd®, Wingtack®, Cleartack® and Dymalink®, our resins are known for consistency and quality our customers trust.
Cray Valley focuses on the rubber and adhesives markets and supports new opportunities in electronics, coatings, and polymer modification. Our technologies allow us to develop products that bring needed properties to the market, including rheology control, crosslinking, adhesion, sealing, and dispersion, or provide backbone structures for polymer synthesis or use as reactive intermediates.
Continuous improvement and technology innovation enable Cray Valley to capitalize on new product development and manufacturing excellence. These synergies provide increased value to our customers and the markets they serve.
Cray Valley has developed a portfolio of products for the tire industry. Ricon® liquid polybutadiene resins are established as performance-enhancing additives for tire tread compounds requiring specific recipes for different segments — winter, summer, all-season, racing, and specialty. Ricon resins modify the viscoelastic properties of these compounds to optimize the balance of traction, fuel economy, and durability.
Cray Valley is a trusted provider of Dymalink® metallic monomers and Ricon functional resins that manage crosslinking, adhesion and dynamic properties for belt, hose, seal, wire and cable, and other industrial rubber applications. Our specialty additives deliver high modulus, hardness, and abrasion resistance to help belts retain their original properties over millions of revolutions. They enhance strong, lightweight hoses with excellent thermal, corrosion, and chemical resistance. They impart rubber adhesion to metals and reinforcing textiles.
Cray Valley offers a wide range of products to enhance adhesion in your performance applications. Our well-known Wingtack® hydrocarbon resins are extremely consistent, high-quality, low-color resins. Based on C5 chemistry, they act as tackifiers in hot melt and pressure-sensitive adhesives. Cleartac®k pure monomer resins provide styrenic end block reinforcement in SBC adhesive formulations while imparting low color and tack to hot melt adhesives.
Ricon® resins improve rubber adhesion to a variety of substrates, such as copper and textile, while increasing the crosslink density of the formulation. Dymalink® resins will dramatically increase the adhesion of rubber to metal substrates, even brass. We also offer C4 resins with a variety of functionality, including hydroxyl-terminated, epoxidized, silylated, and maleinized polymers. The resins offer great formulating latitude in reactive adhesives.
Our Poly bd® hydroxyl-terminated polybutadiene resins offer unique properties in potting and encapsulation formulations. Cured as urethanes, these resins impart good thermal cycling up to 125°C, excellent hydrolytic stability, and low moisture permeation. Poly bd formulations show consistent elongation and embedment stress, even at low temperatures.
Ricon® resins can be used in copper-clad laminate (CCL) applications to improve electrical properties. When used in methacrylated PPE formulations, Ricon copolymers can replace some, or all, of the TAIC hardener. The Ricon resins will improve toughness while improving the dielectric properties of the formulation. Ricon copolymers have the appropriate balance of backbone chemistry and processable viscosity needed to meet the increasing demands of this industry.
Cray Valley products provide important advantages for thermoplastic and thermoplastic elastomer (TPE) applications. Dymalink® metallic monomers increase melt strength in polypropylene-containing polymers and elastomers. This is important for producing products that are formed from extruded foam, sheet, and film. It also adds value for “upcycling” scrap material. Dymalink aids in the manufacture of extruded foam polystyrene sheet. The material's improved melt strength allows for significant light-weighting while maintaining packaging performance.
Ricon® and Cleartack® resins and Dymalink monomers participate in the enhancement of processability, mechanical, and adhesion properties for TPE and vulcanizates used in emerging automotive, fluid handling, construction, consumer goods, and wire and cable industries.
From athletic surfaces to rocket motors, our Poly bd® resins find utility in applications where high filler loading is required. The resins impart the low-temperature flexibility, moisture resistance, and acid/base resistance critical to these formulations. Our C4 resins are reactive plasticizers in specialty applications such as printing plates where formulators can dial in hardness, chemical resistance, and resiliency. Our resins also act as oxygen scavengers in packaging applications, protecting food, juices, and medications from degradation.
Our goal in specialty markets is to work with each customer to develop value-added products that provide solutions to their formulation challenges.
