At present, there are six trends of modified plastics for household appliances. Mainly:

The appearance color is more bright \ environmental protection, the safety module index continues to improve, the automobile is transitioning to the lightweight of household appliances, the health module is initially reflected, low cost is the eternal theme, and energy-saving and low-carbon materials.

1. Appearance color module solution

Technology and fashion personalized color home appliances have become the inevitable trend of current development. The main solutions are:

1) Use bright, high gloss, scratch resistant materials, etc;

The materials are more colorful, such as bright black, purple red, light green, bright red, navy blue, etc.

2) Spray free series - pearlescent, metallic, etc;

It can make plastic products achieve the same effect as silver white, earthy gold, silver gray and other metals, without spraying and electroplating.

3) Other special effects - marble, crystal flow color;

Make the color of plastic products reach the same effect as marble or granite.

2. Safety material module solution

Safe household appliances have become the basic element of current development.

1) High flame retardant material, halogen-free low smoke material

Such as refrigerators, air conditioners, washing machines, motor boxes and other internal or external components, low smoke bromine and phosphorus combined with 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 and gwit850 ℃.

2) High performance materials

Permanent antistatic color pp/abs/ps are used in refrigerators, air conditioners, washing machine shells, etc. Abs/pp/pa/pbt with high flame retardancy and high leakage trace is applied to the electric control part; Conductive pp/abs/ps/pbt, etc. shall be applicable to internal functional components. Meet the requirements of white permanent antistatic 109 and high CTI value (600V).

3. Lightweight material module solution

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

1) Replace glass with plastic, which is a highly transparent and rigid material

High transparency pp/abs/pmma/petg/pes/psf and other components in the observation window can meet the requirements of food hygiene or scratch / strength on the basis of transparency.

2) Plastic instead of steel, high strength, high hardness, 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 and washing machines; 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, cooking resistance and temperature resistance of structural members; In addition, under the same strength, microporous foaming materials can significantly reduce the weight of household appliance shell plastic, have higher strength and processing performance, and will not warp and shrink.

4. Health material module solutions

The concept of health has become a fashion in the development of household appliances.

1) Antibacterial / mildew resistant materials

The addition of inorganic environmental protection composite antibacterial masterbatch or organic polymer antibacterial materials should meet the antibacterial requirements and cannot introduce secondary pollution (AG, as ions). They can be used for internal parts or external parts, such as refrigerators, air conditioners and washing machines.

2) Non toxic and environmental friendly materials

Low VOC volatile materials (pp/ps/abs, etc.) are used in the internal and external components of household appliances; Use plasticizer free elastomer materials (tpe/tpv) for door seals and gaskets. In addition, VOC standard requirements for household appliances are being promoted.

3) Environmental friendly adsorption material

PM2.5 adsorption materials (such as visekasone filling), formaldehyde adsorption materials (activated silicon / alumina filling), negative ion release materials can be used for internal and external parts of household appliances.

5. Low cost material module solutions

Low cost has become an urgent need for the development of household appliances.

1) New cheap functional materials

Use cheap polyolefin materials, such as high gloss PP instead of ABS, abs/pvc instead of flame retardant ABS;

The function of parts is to replace steel, copper, glass and aluminum with plastic, and replace electroplated metal parts with mirror PPS with high glass fiber content;

Environmental friendly high-performance recycled plastics (pp/ps/abs, etc.) are replaced with new materials, which comply with the environmental impact assessment tool of American EPEAT electronic products.

2) Under the condition of constant intensity, the power consumption is reduced

Microporous foam structural materials (pp/abs/ps, etc.) are used in the internal parts of household appliances;

The application of 3D printing materials (fdm/sla/sls) in household appliances can make samples quickly and reduce research and development costs;

Optimize the product structure design through cad/cae, optimize the design of internal and external components and products of home appliances, and reduce consumption.

3) Industry chain integration: modified plastics customized by petrochemical manufacturers

Petrochemical manufacturers cooperate with modification enterprises to customize specific materials:

High gloss abs/ps/pp

Transparent abs/ps/pp

Self flame retardant pa6/pa66, long chain nylon, ASA.

6. Energy saving low carbon material module solution

1) New low carbon functional materials

Low carbon has become an inevitable trend in the development of household appliances. Biodegradable materials and their alloys (starch, PLA) can be used, and the packaging or non structural parts of electrical appliances can be used; Natural fiber reinforced material (PP) can be used to replace glass fiber reinforced material; Ps/abs/pa can be replaced by polypropylene with high heat resistance, weather resistance and rigidity, such as PS framework of air conditioner. This is mainly because the carbon emission index of polypropylene is the lowest (1.95) among the modified plastics used in household appliances. The development trend of polypropylene composite low carbon can reduce the cost.

2) Energy saving and noise reduction functional materials

Thermoplastic elastomer materials (pvc/tpv/tpe, etc.) are used for sealing and shock absorption of household appliance components;

Low noise fan adopts microporous foaming material (increase coaxiality and improve dynamic balance);

The compressor damping pad is made of high damping damping elastomer material to reduce noise.
