Material Expertise
Material guidance starts with the process
Thermosets, engineering thermoplastics and dual-laminate construction for demanding corrosion-resistant applications.
Request Material ReviewEngineering review required. Material suitability depends on chemical concentration, temperature, pressure, mechanical load and service conditions. General properties are not universal operating limits.
Composite material capability
Materials translated into durable equipment
AMPAR combines material selection with controlled fabrication to produce corrosion-resistant piping and process equipment for reviewed chemical, temperature, pressure and mechanical conditions.
The finished system depends on more than the base material. Resin systems, reinforcement, liner construction, wall thickness, joining methods and quality controls must work together for the intended service.

1. Thermoset Plastics
Permanent cross-linked structures
Thermoset plastics begin as resins and harden through heat or a chemical curing reaction. Curing creates permanent cross-links that hold the molecular structure in place, so the finished material cannot be melted and returned to its original liquid state.
Their structural integrity and resistance to heat and chemicals make thermosets valuable in composite process equipment, electrical housings and other demanding applications.
Limitations
- Cannot be reshaped or remoulded after curing
- Generally cannot be recycled through remelting
- Excessive heat may cause degradation rather than melting
2. Thermoplastics
Heat-formable engineering polymers
Thermoplastics are solid at room temperature and soften when heated beyond their melting or glass-transition range. Because processing does not create permanent cross-links, they can be reheated, formed and, in many cases, recycled with limited impact on their material properties.
Extrusion, thermoforming and injection moulding produce components with useful elasticity, strength and chemical resistance. Their temperature sensitivity must be reviewed for every application.
