Product Description
Product Description
Product Composition
The composition of UPGM203/GPO-3 unsaturated polyester glass fiber mat reinforced laminate is based on alkali-free glass fiber mat + unsaturated polyester resin, and functional additives are used to optimize flame retardancy, arc resistance and environmental protection performance. Its composition design is directly related to international standards (IEC 60893, UL 94 V-0), and strictly avoids harmful substances to ensure safety and reliability in high-voltage electrical appliances, UPS systems and other scenarios.
Performance Characteristics
1. Electrical insulation
Arc resistance ≥180 seconds, anti-tracking CTI ≥600V, high resistivity (volume ≥10¹⁰ Ω·m), dielectric strength ≥12 kV/mm.
2. Flame retardant and heat resistance
UL 94 V-0 grade self-extinguishing flame retardant, oxygen index ≥30%, combustion smokeless and halogen-free (in line with French NF standards).
Heat resistance 155°C, operating temperature range -273°C to +155°C, thermal shock resistance.
3. Mechanical and processability
High strength and impact resistance: bending strength ≥180 MPa, impact ≥60 kJ/m², dimensional stability (thermal expansion coefficient ≤21×10⁻⁶/K).
Easy to process: support stamping, CNC, etc., no stratification on the edge, suitable for automated production.
4. Safety and environmental protection
Halogen-free and low-toxicity: Passed RoHS/Reach certification, combustion without irritating gas
Advantages
1. Top electrical performance
Arc resistance ≥ 180 seconds, leakage resistance CTI ≥ 600V, dielectric strength ≥ 12 kV/mm, ensuring the insulation reliability of high-voltage equipment.
2. Flame retardant and heat resistant
UL 94 V-0 self-extinguishing flame retardant, smokeless and halogen-free combustion (NF certified), heat resistant to 155°C, working temperature range spanning -273°C to +155°C.
3. High strength and easy processing
Bending strength ≥ 180 MPa, impact resistance without cracking, dimensional stability (thermal expansion coefficient ≤ 21×10⁻⁶/K), supports efficient processing such as stamping and CNC.
4. Safety and environmental protection
Halogen-free and low-toxic, RoHS/Reach certified, burning without irritating gases, suitable for confined spaces.
Summary: With "electrical insulation + flame retardant and heat resistant" as the core, it has both strength and environmental protection, and is specially used in high-demand scenarios such as circuit breaker partitions, arc extinguishing covers, motor carbon brush holders, etc.
Application Fields
1. Circuit breaker components
Arc extinguishing system: arc extinguishing chamber arc isolation plate, phase partition (flame retardant V-0 level arc blocking)
Safety structural parts: safety baffles and spacer pads of frame-type circuit breakers (dimensional stability ensures precise assembly)
2. Motor and motor components
Stator/rotor components: slot wedges, fixed gaskets, carbon brush holders (impact resistance ≥60 kJ/m², vibration-proof and fragmentation-proof)
High-temperature components: movable cover plates, thin gaskets (heat-resistant 155℃ to adapt to high-temperature motor environments)
3. Switchgear and power transmission and distribution
Isolation support: busbar support, high-voltage insulator (CTI ≥600V leakage resistance, arc resistance ≥180 seconds)
Cabinet structure: switch cabinet partition, contact support (bending strength ≥180 MPa to ensure rigidity)
Summary: Core applications: Circuit breaker arc extinguishing, motor heat-resistant components, high and low voltage switch isolation Three major scenarios, using electrical insulation + mechanical support functions to solve the needs of high voltage, strong vibration, and high temperature working conditions.
