This technology results in high-performance cores capable of withstanding significant mechanical stress while maintaining dimensional stability. In this article, we take a closer look at the technology and science behind these cores.

Composition of PEHD R Mineral C

PEHD R Mineral C is a composite material created by integrating mineral fillers into the High-Density Polyethylene (HDPE) matrix. These fillers, such as calcium carbonate or silica, modify the HDPE’s structure at a molecular level, acting as reinforcement points within the polymer matrix.

This combination offers several key benefits:

• Enhanced mechanical strength: The addition of mineral fillers creates interactions between the mineral particles and the HDPE polymer chains, increasing resistance to deformation under stress. This reduces ovalisation and creep.
• Optimised load distribution: Mineral fillers help distribute mechanical stress throughout the material. As a result, PEHD R Mineral C cores can withstand higher forces while remaining dimensionally stable.
• Increased rigidity: The material’s rigidity improves with the addition of minerals, making it highly suitable for cores used in industrial environments with high mechanical stress.

Extrusion Technology for PEHD R Mineral C

PEHD R Mineral C cores are manufactured using a plastic extrusion process. This involves melting and homogenising HDPE and mineral fillers before forcing the mixture through a die to form the cores. This process requires precise control of several scientific parameters:

• Melting and homogenisation: HDPE and mineral fillers must be melted at a sufficiently high temperature to ensure complete fusion without degrading the components. The viscosity of the molten material must also be controlled to allow for uniform extrusion.
• Uniform dispersion of mineral fillers: The fillers must be evenly distributed within the polymer matrix to ensure consistent mechanical properties throughout the core.
• Crystallisation control: HDPE is a semi-crystalline polymer, meaning its molecular chains can align in crystalline zones. Cooling must be controlled to promote crystallinity, which enhances the material’s rigidity and overall strength.

Industrial Applications of PEHD R Mineral C Cores

PEHD R Mineral C cores are particularly well-suited to industries where mechanical and thermal stress levels are high. Some common applications include:

• Plastic film industry: These cores enable stable winding of technical plastic films while resisting deformation under the pressure of the wound material.
• Industrial packaging and technical adhesives: PEHD R Mineral C cores meet precision and strength requirements in environments where significant forces are applied to the cores.
• Other demanding industrial sectors: These cores are also used in industries where durability and precision are crucial, such as the automotive and electronics sectors.

A Durable and High-Performance Solution

PEHD R Mineral C cores offer superior durability due to their increased resistance to wear and mechanical stress. This longevity helps reduce maintenance and replacement costs.
Additionally, the composite material is recyclable, making it an environmentally friendly option for industrial companies.
