Customized Compounds & Masterbatch
RKW is a leading manufacturer of highly filled compounds for food packaging and other industrial applications. The company offers customized solutions by using high-quality polymers as carriers for various minerals and additives, enhancing the properties of packaging materials and end products. RKW can deliver products that improve performance and reduce production costs.
Calcium Carbonate Compounds
Whether you're working to reduce your carbon footprint or lower costs, calcium carbonate (CaCO₃) has a role to play.
By utilizing naturally occurring minerals, with minimal environmental impact, both goals can be achieved. The increased processability of both virgin and recycled polymers is a positive side effect.
Adding CaCO₃ to polyolefins provides several benefits:
- Improves the material's mechanical properties, such as stiffness and tensile strength, enhancing overall performance.
- Reduces production costs by acting as a low-cost filler that partially replaces more expensive polymers.
- Enhances the processing characteristics of polyolefins by improving flow properties during extrusion and molding.
- Improves the material's dimensional stability, making it less prone to warping.
- Contributes to better opacity, making it ideal for packaging applications and other commercial uses.
Talc Compounds
Are you working to increase impact strength or a higher E-modulus for your product? Using talc compounds from RKW is a sensible choice, especially for extruding film for thermoforming, but also for bottle blowing or injection molding.
Adding talc to polyolefins provides several significant benefits:
- Improves the mechanical properties of polyolefins, such as increasing stiffness, impact resistance, and dimensional stability.
- Enhances the material’s heat resistance, making it suitable for applications requiring higher temperature performance.
- Acts as a nucleating agent, improving the crystallization process and leading to faster cycle times.
- Offers better processability, particularly in extrusion and injection molding, making them ideal for applications such as automotive parts, packaging, pipes, and consumer products.
White Masterbatch
White masterbatch is a cornerstone of the plastics industry. Adding white masterbatch to polyolefins offers many benefits, particularly in enhancing the visual and functional properties of the material:
- Provides excellent opacity and ensures a bright white finish that improves the aesthetic appearance of the end product.
- Helps achieve a uniform color, preventing variations during production.
- Can improve UV resistance and stability, extending the material's lifespan when exposed to sunlight.
- Reduces the need for additional pigmenting, making it a cost-effective and
efficient solution for various polyolefin applications.
Producing customized white masterbatch for specific applications allows RKW to add value to your final product.
Additive Masterbatch
Additive
Masterbatch is very commonly used in the plastic industry, especially in
extrusion production. Enhancing the properties in film, profiles and injection
moulded products brings out the best of the raw material and improving end
products. RKW develops a new portfolio of additive masterbatch.
