Application Status and Development Trend of Modified PP in Household Appliances
Polypropylene is one of the preferred plastic varieties in the household appliance industry due to its low density, good chemical resistance, low price, and excellent overall performance, and its consumption accounts for about 30%. With the continuous emergence of personalized and intelligent new home appliances, higher requirements are also put forward for the application and modification of PP in home appliances. The PP modification technology will focus on the following aspects. 1. Green: Compared with traditional spray materials, such as spray-free PP materials, spray-free materials are relatively simple in process, more environmentally friendly and more economical, and have the characteristics of high gloss, easy molding, scratch resistance, and recyclability. There are more and more applications in the field of home appliances, especially spray-free PP materials. 2. Safety: meet the requirements of unattended electrical appliances, flame retardant modified PP materials, etc. meet the requirements of modified PP materials for long-term unattended electrical appliances proposed by the International Electrotechnical Commission (IEC). The IEC60335 standard requires that the glow wire at 750°C does not ignite or burn within 30 seconds of contacting the material or product to be tested.≤5 seconds (ie GWIT≥750℃) and tracking index (CTI)≥250V, polysialon modified PP material can meet. 3. Health: In order to reduce costs, such as anti-dying PP, most of the liner materials of home appliances such as dishwashers or juice machines are produced with modified PP materials. After repeated use, the liner is easy to be dirty. The reason is that the color of the surface of the material changes due to contamination after the liner material is directly in contact with fruit juice, food residue, food seasoning, etc. When the color changes to a certain extent, it will become dirty, and even serve as a source of pollution to contaminate the next batch of food, reducing the product's quality. Use quality. Anti-staining PP can avoid this problem. 4. Lightweight: high continuous long glass fiber content reinforced PP materials such as long glass fiber reinforced PP and micro-foamed injection molding PP materials: it has good dimensional stability, excellent comprehensive mechanical properties, small creep and excellent Fatigue resistance. Micro-foaming injection molding PP material: It refers to the use of polypropylene material as the matrix. Under the action of gas internal pressure through the injection molding process, the middle layer of the product is densely covered with closed pores ranging from ten to tens of microns, and there are dense skins on both sides. structure; so as to achieve the purpose of material saving and weight reduction. Because the micro-foamed material uses lower stress, the injection molding is smoother, straighter, and dimensionally more stable. At the same time, due to the support of the micro-pores, it can effectively solve the part sink marks. 5. Functionalization: The marks used for identification, such as trademarks and barcodes on plastic products such as PP materials that can realize laser engraving, are usually generated by external processing methods such as printing, pasting labels, embossing, punching, etc. The surface printing marking of plastic products is a new type of marking technology with high processing speed, which can maintain the inherent surface characteristics of plastic products and make text and icons never fade. The laser marking machine for plastic products uses a laser beam to directly generate marks on the plastic surface, and the pattern design is flexible and does not require other processing procedures.
If you are a tensile tester manufacturers fan, you definitely want to enjoy the best possible. The that you choose plays a major role with the kind of experience you have when using it.
Our mission is to operate the best specialty retail business in domestic, regardless of the product we sell. Because the product we sell is textile testing equipment, our aspirations must be consistent with the promise and the ideals of the volumes which line our manufacture.
In conjunction with retraining and upskilling efforts, GESTER International Co.,Limited’s workers should focus on growing unique human skills that high-tech machines are unable to replicate, such as strategic and abstract thinking, complex communications, creativity and leadership competencies.
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
