Rubber

Additives enhance the physical properties of rubber, making it more resistant to environmental stressors and increasing its suitability for various demanding applications. See our full list of additives here!

• Antimicrobials prevent the growth of bacteria, fungi, and other microorganisms, extending the life of rubber products in harsh environments.
• Antioxidants protect rubber from oxidative degradation, which can lead to cracking and loss of elasticity over time, especially in high-heat or high-oxygen conditions.
• Hindered amine light stabilizers (HALS) provide superior light stabilization, preventing UV-induced degradation and discoloration in rubber exposed to sunlight.
• Sulfur functional silanes enhance cross-linking in rubber, improving overall durability, elasticity, and resistance to wear and tear.
• UV absorbers absorb harmful ultraviolet light, preventing UV damage that can weaken rubber materials and cause them to break down prematurely.

Mold release agents ensure that rubber components can be easily removed from molds without damage, improving production efficiency and reducing defects.

• LokRelease^® provides superior release performance, minimizing sticking and surface defects during molding, which leads to a higher quality finish and less production downtime.

Performance fillers enhance the physical properties of rubber by improving strength, durability, and processing efficiency, while also reducing production costs.

• Calcium carbonate improves the mechanical strength, stiffness, and processability of rubber, while reducing costs.
• Diatomaceous earth (DE) enhances rubber flexibility and durability, providing excellent heat and chemical resistance.
• E-Spheres^® are lightweight hollow ceramic particles that reduce weight while improving strength and impact resistance in rubber composites.
• Feldspar (Minspar^®) enhances toughness and abrasion resistance in rubber, improving overall durability.
• Fumed silica (Konasil^®) increases tear strength and enhances viscosity control in rubber compounds.
• Kaolin clay acts as a reinforcing filler, improving the tensile strength and heat resistance of rubber.
• Mica 
• Precipitated silica (Tixosil^®, Zeosil^®) provides improved wear resistance, traction, and energy efficiency, particularly in tire production.
• Talc increases heat resistance and reduces surface friction, making rubber smoother and easier to handle.

Pigments provide essential coloring and aesthetic properties to rubber products, while also enhancing performance such as heat resistance and UV protection.

• Aluminum effect pigments add metallic sheen and reflectivity, improving aesthetic appeal in specialty rubber products.
• Iron oxides provide excellent color stability, UV resistance, and heat resistance, making them ideal for outdoor rubber applications.
• Organic pigments, dyes, and dispersions offer vibrant, customizable colors while being environmentally friendly and chemically stable in rubber.
• Titanium dioxide provides high opacity, whiteness, and UV protection, improving the appearance and longevity of rubber products.

Resins play a pivotal role in enhancing the adhesion, flexibility, and processing of rubber compounds.

• Hydrocarbon resins (aromatic - Hikotack^®, aliphatic - Hikorez^®, Sukorez^®) improve tackiness, adhesion, and elongation in rubber, making them ideal for rubber adhesives, sealants, and coatings.

Rubber adhesives are critical in bonding rubber to various substrates, ensuring strong, durable bonds in demanding environments.

• Chemlok^®, rubber to metal adhesive, ensures superior bonding of rubber to metal surfaces, providing high strength and durability in automotive, industrial, and construction applications.

Waxes improve processing, surface smoothness, and release properties in rubber, while also enhancing its overall performance and durability.

• Fisher-Tropsch waxes enhance mold release and surface quality in rubber products, providing superior lubrication and gloss.
