Product Description

Product Description

This system product chooses high purity epoxy resin and high quality liquid anhydride as raw material and adopts APG technology. It is stable in normal temperature. It has the characteristics like: Fast gel at high temperature, good electric and heat performance, etc. 

Proportion 

Epoxy resin QY-8303A 100 part by weight 
Curing agent QY-8303B 100 part by weight 
Filler ATMC 300-350 part by weight 
Mill base Q. S 

Scope of application: High voltage electric insulation parts, such as insulator, insulation tube, mutual inductor, etc. 

Quality index 

QY-8303A modification medium viscosity bisphenol A epoxy resin 

Appearance 
Colorless or nearly colorless viscosity liquid 

Viscosity(PA. S/25 degree) 
≥ 10 

Epoxy value(EQ/100g) 
0.48~0.53 

Can be hydrolyzed chloride(%) 
≤ 0.1 

Density(g/cm325degree) 
1.16~1.18 

Volatile matter(%110degree) 
≤ 0.1 

QY-8303B modification or pre-added accelerate liquid anhydride curing agent 

Appearance 
Light yellow to yellow transparent liquid 

Viscosity(PA. S/25degree) 
0.12~0.15 

Density(g/cm3 25degree) 
1.20~1.25 

Acid value (mgKOH/g) 
≥ 500 

Anhydride Content(%) 
≥ 30 

Note: QY-8303B contained accelerates. So it should be avoided to store at high temperature. It should avoid moisture and not exposure to air for long time. 

Molding parameter 

Mold temperature 140~160degree 
Gelation time 8~11min/140degree, 4~5min/160degree 
Injection pressure 0.2~0.5MPa 
Demould time 15~40min(According to mold temperature and injection parts volume ) 
Post curing More that 10 hours/more than 130degree or 6 hours/140degree 

Curing body main performance index 

Flexural strength(MPa) 125~135 
Tensile strength(MPa) 65~75 
Impulse strength(kJ/m2) 12~18 
Glass transition temperature(degree) 95~105 
Electric strength(kv/mm) 20~28 
Curing shrinkage (%) 0.8~1.0 
Dielectric loss angle tangent(1× 106Hz) 0.01~0.02 
Density(Filler content 60%, g/cm3) 1.75~1.80 

No filler 8303 system viscosity change under 40degree 

The above data is determined by the standard sample according to the national standard method. Glass transition temperature is tested by DSC method. Since the difference of material mixture ratio and technology, the data may have deviation. 

The above data is only for reference.
