Hylam is a rigid phenolic laminate, offering good surface hardness and mechanical strength. Its hardness depends on the type of resin, paper/fabric reinforcement, and processing conditions. Typical Hardness: Shore D: 70–85 (unfilled standard Hylam sheets) Reinforced or specialty grades can reach slightly higher hardness, improving wear resistance and structural rigidity. Effect of Temperature: Hylam maintains hardness up to ~150–160°C; prolonged exposure above this temperature may reduce mechanical strength. Surface Properties: The smooth, hard surface makes Hylam ideal for insulation plates, panels, and machined components.

Hylam is a phenolic laminate, a thermosetting material, and does not undergo traditional metallurgical heat treatment. However, controlled thermal processes can be used to relieve internal stresses, improve dimensional stability, and enhance mechanical performance. 1. Curing / Post-Processing Heat Treatment During manufacturing, Hylam sheets are pressed under heat (140–160°C) and pressure, which cures the phenolic resin, giving the laminate its rigid, heat-resistant structure. Proper curing ensures uniform hardness, electrical insulation, and dimensional stability. 2. Stress Relief / Annealing Machined or fabricated components may be annealed at 120–140°C for 1–2 hours to relieve internal stresses. This prevents warping, cracking, or delamination during service. 3. Important Considerations Avoid exposure above 160–180°C, which can degrade mechanical properties. Hylam maintains its electrical insulation and structural integrity under normal operating conditions.

Hylam is a thermosetting phenolic laminate, and unlike metals, it cannot be hardened through quenching or heat treatment. Its mechanical strength and surface hardness are achieved during manufacturing via resin curing under heat and pressure. Cured Hardness: The pressing and curing process produces a rigid laminate with Shore D hardness typically 70–85, depending on resin type, reinforcement, and sheet thickness. Effect of Temperature: Hardness is stable under normal service temperatures (up to ~150–160°C). Exposure above this range may soften or degrade the material. Surface Reinforcement: Laminates reinforced with glass or fabric layers achieve higher hardness and wear resistance, suitable for mechanical or electrical components.

Welding / Joining – Hylam Hylam is a thermosetting phenolic laminate and cannot be welded like metals or thermoplastics. Joining or assembly is typically achieved using mechanical fastening or adhesive bonding. 1. Mechanical Joining Bolts, screws, rivets, and clamps are commonly used to assemble Hylam components. Care must be taken to avoid cracking or delamination, especially near edges or thin sections. 2. Adhesive Bonding Epoxy, phenolic, or polyurethane adhesives are typically used for bonding Hylam to itself or other materials. Surface preparation, such as light sanding or cleaning, improves adhesion. 3. Important Considerations Avoid excessive stress on joints, as Hylam is brittle compared to metals. Drilling or machining prior to joining should be done carefully to prevent micro-cracks. Reinforced grades (e.g., glass-fabric Hylam) may require special adhesives or primers.

Hylam is a rigid phenolic laminate that is moderately easy to machine, but care must be taken due to its brittle nature. Proper tooling and techniques ensure dimensional accuracy and smooth surfaces. 1. Machining Characteristics Can be drilled, milled, sawn, or turned using tools suitable for plastics or soft metals. Produces fine dust, so adequate dust extraction is recommended. Sharp tools and moderate feed rates prevent chipping or delamination. 2. Factors Affecting Machinability Thickness and Reinforcement: Glass-fabric reinforced Hylam is more abrasive and requires harder cutting tools. Tool Selection: Carbide-tipped or high-speed steel (HSS) tools are preferred. Temperature Sensitivity: Avoid excessive heat generation to prevent resin softening or surface discoloration. 3. Practical Tips Drill pilot holes to reduce stress on edges. Use low to moderate spindle speeds for milling or turning. Allow for post-machining stress relief if tight dimensional tolerances are required.
