Flexible resins operate continuously at 155C and fulfil the stringent Class F requirements.
Polyurethane resin specialist ALH Systems has developed a unique range of flexible resins that operate continuously at 155C and fulfil the stringent Class F requirements.
The polyurethane resins do not suffer either reversion or oxidation at elevated temperatures making them suitable for under-bonnet automotive applications.
The NP1850 low-viscosity system cures to a Shore A hardness of 87.
The softer NP1851 is intumescent and is already being applied in electronic ignition systems.
The great advantage of these polyurethane resins is the flexibility in the curing and performance characteristics.
Future variants in this range will include a high thermal conductivity and flame-retardant product.
