Product catalog summary
Overview: The document provides a comprehensive analysis of Plascore PP Honeycomb, an engineered polypropylene core material known for its lightweight, strength, and cost-effectiveness. It is designed for use in composite sandwich structures, offering an alternative to traditional materials like plywood, balsa, and foam.
Specifications: The PP Honeycomb features a multi-axial structure for isotropic performance, engineered raw materials for enhanced performance, and a uniform cell structure. It is compatible with various resin systems, recyclable, and available in densities ranging from 3.5 to 20.0 pcf and thicknesses from ¼" to 6" laminated, with open cell options up to 24". It meets ISO-9001 quality standards.
Mechanical Properties: The document lists mechanical properties such as density, tensile strength, compression strength, and modulus, tested per ASTM standards. The core is available in different configurations and densities, with specific mechanical properties outlined for each.
Applications: PP Honeycomb is suitable for thermo-plastic molding, air and fluid flow mediums, and various molding processes like open molding, platen press, and vacuum bagging. It is also used in closed molding processes such as Lite RTM and vacuum infusion. It is recommended for applications with moderate loading and unsupported spans of 24" or greater.
Processing Guidelines: The document provides guidelines for bonding, molding, and fabricating the PP Honeycomb, emphasizing temperature control during the molding process to prevent melting and structural loss.
Value-Added Configurations: The core is available in configurations with different facings, such as non-woven polyester, composite surfacing material, and reinforced-PP stress skins, each tailored for specific applications and processes.
Performance Comparison: The document includes comparative data on cost, density, and performance against other materials like balsa and PVC foam, highlighting the PP Honeycomb's advantages in terms of cost-effectiveness and mechanical performance.
Key Performance Criteria: Plascore PP Honeycomb is noted for its cost-to-performance value, efficient sound absorption, moisture resistance, and continued performance after failure. It is unaffected by most chemicals and provides positive buoyancy.
Performance Under Stress: The material efficiently absorbs energy and dissipates vibration, making it suitable for applications requiring lightweight and rigid structures. It maintains performance even after reaching ultimate yield strength.
Environmental and Chemical Resistance: The honeycomb is resistant to moisture and most chemicals, although specific chemical concentrations and temperature variables may affect resistance.
Flammability: The material is flammable when tested to UL94 Horizontal Burn but can achieve various flammability ratings when used with different stress skins.
Storage and Handling: It is recommended to store the material flat, horizontal, and in a dry, covered area to prevent moisture absorption and UV damage.
Contact Information: Plascore provides contact details for their corporate headquarters in the USA and their European office in Germany for further inquiries and sales.
