Six trends in modified plastics for home appliances

With the advancement of plastic instead of steel, the home appliances around us are quietly plasticizing. In the interior of home appliances, screws, gears and other structural parts began to use plastic materials; in the exterior of home appliances, plastic plasticity can become any appearance. The "internal and external repair" of plastics in home appliances is actually attributed to a technology-modification.

With the development of plastic modification technology and the improvement of people's living standards, modified plastics are more and more widely used in the home appliance industry, kitchen utensils, personal care and other products, all use modified plastics.

Taking small household appliances as an example, common small household appliances include electric pressure cooker, induction cooker, noodle machine, steamed bread machine, soybean milk machine, cooking machine, juicer, boiling water cooker, hair dryer, hair straightener, shaver and so on. Small household appliances in the process of frequent contact, easy to wear, long-term contact with water, oil, salt, easy to corrode, long-term use in high temperature state, easy to age, long-term light, easy to change color, lose luster, so the material appearance performance is strong, good scratch resistance, easy processing, high cost performance.

How to rationally apply modified plastic materials to reduce the cost of small household appliances and ensure product quality is one of the important ways for products to occupy the market.

Common small household appliances plastic material selection

(1) Microwave oven

The plastic parts on the microwave oven are mainly external parts, including shell, base, handle, knob, etc., which require heat resistance.

The plastic materials selected are heat-resistant ABS, flame retardant HIPS, heat-resistant PP, PC/ABS alloy, etc.

(2) rice cooker

The plastic parts on the rice cooker are mainly external parts, including shell, base, cover, handle, switch, etc., which require heat resistance.

The selected plastic varieties are spray-free ABS, high gloss PP.

(3) air humidifier

The plastic materials selected are: dyed ABS, spray-free materials, transparent parts (PC, GPPS), high-gloss PP.

Main materials for appearance parts

Dyeing ABS: heat resistance, high surface gloss, stable size, easy to process, easy to spray, can be made into different colors according to requirements;

PP plus filling: low cost, good fluidity, stable size and easy processing;

PC material: high strength, high temperature resistance, good transparency;

PC/ABS alloy: heat resistance, good surface gloss, dimensional stability and easy processing.

Main materials for decorative parts

Transparent material: transparent ABS, PMMA, PC, etc;

Electroplating material: electroplating grade ABS;

Spray-free materials: high-gloss spray-free ABS, spray-free AS, spray-free PC/ABS, spray-free PP;

Spray-free material has the characteristics of high gloss, metallic color, good processability, bright color, good fluidity and scratch resistance.

Six trends in modified plastics for home appliances

Appearance color module solution

Technology, fashion personalized color home appliances has become the inevitable trend of development. The main solutions are:

(1) Use bright, high-gloss, scratch-resistant materials, etc.

Material color is more rich, such as: bright black, purple, green, brilliant red, blue and so on.

(2) No spraying series-pearlescent, metallic, etc.

Can make plastic products without spraying plating to achieve the same effect of silver white, gold, silver ash and other metals.

(3) other special effects-marble, crystal flow color marble, crystal flow color

The color of plastic products to achieve the same effect as marble or granite.

Secure Material Module Solutions

Safety appliances have become the basic elements of the current development of safety appliances has become the basic elements of the current development.

(1) High flame retardant materials, halogen-free low smoke materials

For example, internal or external parts such as refrigerators, air conditioners, washing machine motor boxes, etc. are made of low smoke bromine-phosphorus synergistic high flame retardant PP/ABS/PS or low smoke halogen-free flame retardant PP/ABS/PS/PBT and other materials, meeting the requirements of 1.5mm 5VA, GWIT850 ℃, etc.

(2) High-performance materials

Permanent antistatic color PP/ABS/PS, etc. are applied to refrigerators, air conditioners, washing machine housings, etc. High flame retardant and high leakage mark ABS/PP/PA/PBT, etc. are applied to electric control components; Conductive PP/ABS/PS/PBT, etc. are applied to internal functional parts. Meet the white permanent antistatic 109, high CTI value (600V) and other requirements.

Lightweight Material Module Solutions

It is an inevitable trend to extend lightweight products from automobiles to home appliances.

(1) to plastic instead of glass, high transparency and high rigidity material

High transparent PP/ABS/PMMA/PETG/PES/PSF, etc. are used on the observation window and other parts to meet the requirements of food hygiene or scratch resistance/strength on the basis of transparency.

(2) to plastic instead of steel, rigid strength, high hard dimensional stability material

High-strength materials with high glass fiber content (>50%) and long glass fiber reinforced materials (LFT-PP/PA) are used in technical structural parts such as refrigerators, air conditioners, washing machines, etc. Glass fiber reinforced special engineering materials (PPS/PEI) are used in wear-resistant parts. These materials meet the requirements of high strength, high wear resistance, boiling resistance and temperature resistance of structural components. In addition, under the same strength, the microcellular foaming material can significantly reduce the weight of the plastic for household appliances, and has no warping and shrinkage marks, and has higher strength and processability.
