Flame Retardant of Injection Plastic Parts
The flame retardant in the shape of the powder is unevenly scattered during the processing process, and the product often appears. Therefore, it is suitable for plastic modified plants to modify granules. And other additives need to be added for completion and formula design. Customers who want to process the finished product are not applicable to choose a powder flame retardant. Customers who need to directly injection can choose PP flame retardant parent grains. It is the concentrated parent granules of the composite formula of the PP flame retardant. It has a carrier and a composite flame retardant.
How the flame retardant is applied during the injection molding process?
1. The decomposition product of the injection molding flame retardant under the combustion will form a glass film that is oxidized and underage. The glass film can isolate the air's reflection or has a lower thermal conductivity.
2. After heating and decomposition, dilute the fuel gas and dilute the burning oxygen concentration.
3. Plastic processing flame retardant melts and releases heat.
4. Form a porous insulation layer on the surface of the product to prevent heat transmission and burning.
Commonly materials for injection molding | ||
Materials | Advantages | Disadvantages |
Polystyrene (PS) | Good optical and coloring performance, excellent electrical performance, easy molding and processing. | Low heat resistance temperature (Max is 60~80 ℃), and poor acid resistance. |
Polypropylene (PP) | Good fluidity and electrical performance, excellent formability and heat resistance. | Poor fire safety and weather resistance, sensitive to oxygen, susceptible to aging due to ultraviolet rays. |
Nylon (PA) | High mechanical, tensile and compressive strength, good toughness, outstanding fatigue resistance, wear resistance, corrosion resistance, heat resistance, non-toxic, excellent electrical properties | Poor light resistance, easy to absorb water, not acid resistant |
Polyoxymethylene (POM) | High elastic modulus. Small friction coefficient, excellent wear resistance and self-lubrication. Good solvent resistance, especially organic solvent. Good dimensional stability, can manufacture precision parts. | Not strong acid, alkali and oxidant. Large molding shrinkage, poor thermal stability, easy to decompose when heated. |
ABS (Acrylic Butadiene Styrene) | High mechanical strength, strong impact resistance, good anti-creep. It’s hard, tough and rigid. | Heavy weight, poor thermal conductivity, strong moisture absorption and poor heat resistance. |
Polycarbonate (PC) | It has the best impact strength among all thermoplastic materials. Excellent creep resistance, good dimensional stability and high molding accuracy; Good heat resistance (120 ℃) | Low fatigue strength, high internal stress, easy to crack, poor wear resistance of plastic parts |
PC+ABS (PC/ABS alloy) | It contains ABS and PC chemical components, has good fluidity and molding processing performance of ABS, and PC is resistant to impact and cold and hot cycle changes. | Tensile strength, elongation and hot deformation temperature decreased, viscosity increased, and fluidity decreased |
