With the emergence of personalized and intelligent new home appliances, the application of PP in home appliances has also been put forward with higher requirements. The PP modification technology will be developed around the following aspects.
One, green
Poly-Ryron green materials are free from spray PP modification, easy to clean modified PP, etc. Non-spray PP material comes with different display colors, through direct injection molding, can achieve black and bright, metal, flicker, extinction, natural texture and other effects , Compared with the traditional spraying material, spray-free PP material can solve the complex process, low yield, solvent pollution and other issues. Easy to clean modified PP material through the super-hydrophobic surface modification, so that the product to achieve the effect of easy cleaning.
Second, security
The SAFETY material satisfies the requirements of the International Electrotechnical Commission (IEC) for long-term unattended use of modified PP materials. The IEC 60335 standard requires that the 750°C glow-wires contact the material or article under test within 30 seconds without burning or burning time ≤ 5 seconds. (ie GWIT ≥750°C) and CTI ≥250V.
Third, lightweight
Polysilicon lightweight PP materials have high continuous length glass fiber reinforced PP materials and modified PP materials suitable for micro foaming requirements. Long glass fiber reinforced materials have good dimensional stability and excellent comprehensive mechanical properties. Small creep and excellent fatigue resistance. Micro-foamed PP material refers to the polypropylene material as the matrix, under the pressure of the gas under the action of the injection process, so that the middle layer of the product from the size of ten to several tens of microns closed The micropores on both sides have a dense skin structure; thus achieving the purpose of saving material and weight. Since the micro foam material uses a lower stress, the injection molding is smoother, more straight, and the size is more stable, and at the same time, due to micropores The support function can also effectively solve the part sink marks.
Fourth, health
Julong Health Series PP material has antibacterial PP, anti-dye PP, low odor modified PP and so on.
V. Functionalization
Poly-Relon functionalized materials include easy-to-apply modified PP, etc. Easy-to-paint modified PP materials are directly modified by blending, introducing polar functional groups to form co-crystals with polypropylene resin, avoiding precipitation, and avoiding weaknesses. The formation of the interface layer, so as to improve the surface tension as a whole.
