In polyurethane production, the PC-5 catalyst is key to faster reaction times, better foam formation, and superior material quality. Specific applications and instructions are detailed below:
一、Core mechanism of action：
- Accelerate the reaction
PC-5 reduces the activation energy of isocyanate and polyol by generating intermediates, significantly shortens the foaming time and improves production efficiency. - Control the foaming process
Regulate the foaming speed and cell structure to ensure material uniformity, thereby optimizing key parameters such as density, hardness and resilience.
二、Main application areas：
- Polyurethane rigid foam products
Construction field: used for polyisocyanurate sheet rigid foam, improve foam fluidity, improve production process and production volume. - Car seats: balance softness and support to improve riding comfort.
Nuclear energy/pipeline insulation: enhance thermal insulation performance through uniform pore structure (thermal conductivity can be reduced to below 0.020 W/(m·K)), reduce energy loss. - Other fields
Including agricultural greenhouse covering materials (transparent, tough and durable) and office furniture surface treatment (improve gloss and chemical resistance).
三、Usage and dosage：
- Dosage range: 1.0-2.0 parts PC-5 per 100 parts polyol.
- Common combinations: Often used with catalysts such as DMCHA to synergistically optimize the reaction effect.
四、Advantages and features：
- High efficiency: significantly shortens the curing time (e.g. from 8-12 hours to 2-4 hours).
- Stability: acid and alkali resistance, wide pH range, and not prone to side reactions.
- Versatility: can adjust both physical properties (hardness, density) and chemical properties (durability) at the same time.
