Technical knowledge popularization | Types and applications of modified flame retardant PP plastics

First, flame retardant PP plastic types

PP plastic has the characteristics of low density, non-toxic colorless, odorless, corrosion resistance, high temperature resistance, the use of flame retardant modification, suitable for household appliances, automobiles and other industries have flame retardant components to meet the needs of electrical products, in addition to achieve the best economic benefits. At present, several common types of flame retardant PP plastics are environmentally friendly flame retardant PP, halogen-free flame retardant PP, high glow wire flame retardant PP, high CTI flame retardant PP plastics.

1, halogen-free flame retardant PP plastic

Halogen-free "halide" refers to the halogen elements in the list of chemical elements, including fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and (Ts). Halogen-free flame retardant PP plastic additives mainly phosphorus compounds and metal hydroxide account for the majority, halogen-free flame retardant PP materials when burning smoke amount is small, low density, low cost input, the formation of toxic, corrosive gas is also relatively small, mainly used for small household appliances shell, such as iron, hair dryer and other electrical parts.

2, high burning wire flame retardant PP plastic

High hot wire performance means that the product has a safer performance index. High glow wire flame retardant PP plastic can meet the glow wire 850℃ non-combustible, flammability index reaches 960℃, suitable for capacitors, plugboards and so on.

3, high CTI flame retardant PP plastic

The flame retardant V0 grade PP material with high CTI characteristics is halogen-free and flame retardant, the burning temperature of the hot wire can reach 850 ° C, the flammability index can reach 960 ° C, the fluidity is high, and the molding effect is excellent, which just meets the current standard of intelligent home appliances for materials. It is widely used in LED lamp casing, capacitor casing, electrical structure parts, microwave oven internal bracket, plug board casing, heater casing and other electrical appliances.

Second, the application industry of flame retardant PP plastics:

The technical application of flame-retardant PP plastic has become increasingly mature and stable, and it is fully applicable to electronic materials, household appliances, automobiles and other fields. If there are flame-retardant automotive parts, flame-retardant household appliance parts such as power supply, heater shell switch, electric kettle base, terminal block, household appliance shell, microwave oven shell, induction cooker shell, motor base, washing machine parts, electric iron parts, electric oven parts, etc.

Flame retardant PP plastic for washing machine: The motor housing in the washing machine is mainly for the motor of the washing machine to play a stable and protective role. In the whole process of high-speed dehydration of the washing machine, some parts are easy to generate sparks because of vibration friction, so it is convenient for the motor to be more safe and stable operation, and many manufacturers have given flame retardant standards to the motor housing materials. The use of flame retardant PP material can not only meet the flame retardant standard, but also meet the mechanical properties, thermal properties and other needs, and has cost advantages.

Flame retardant PP plastics for intelligent home: With the development of electrical automation technology, the number of frequently unattended intelligent home appliances is increasing, which provides a new standard for the materials used in electrical appliances. High glow-wire High CTI flame retardant PP plastic glow-wire ignition temperature can reach 850 ° C, flammability index reaches 960 ° C, high fluidity, excellent molding effect.
