Core Product Advantages

Balanced Rigidity and Flexibility

Yanchang V30G strikes a favorable balance between rigidity and dimensional stability. This characteristic is particularly useful in applications where assembly precision is required, such as home appliance shells and automotive interior parts. It can effectively maintain the shape and size of products, reduce deformation during use, and extend the service life of the finished products.

Good Chemical Resistance and Low Moisture Absorption

The product has good resistance to dilute acids, dilute alkalis, water and alcohols, which means it can withstand exposure to such common substances without significant performance degradation. It should be noted that the product is not resistant to strong organic solvents such as aromatics and esters, and is not suitable for use in harsh chemical environments.

Excellent High-Flow Molding Performance

With a moderate melt flow rate of 15 g/10min, Yanchang V30G has excellent melt fluidity and uniform plasticization performance. In injection molding lines for daily goods and auto interior parts, it maintains stable continuous production state and lowers the occurrence rate of molding defects including short shots and voids, stabilizing finished product yield under standardized production parameters. 

Environmental Protection and Food Contact Safety

Yanchang V30G is made of 100% virgin PP material, with low odor and no harmful substances released during processing and use. More importantly, it meets the requirements of food contact safety standards, which is essential for applications in food packaging containers and daily necessities that come into contact with food. It ensures that the finished products do not contaminate food or affect human health, meeting the strict safety requirements of the food and daily necessities industries.

Main Application Fields

Daily Necessities Industry

Relying on its good molding performance, low odor and food contact safety, it can be used for making various daily plastic products, such as plastic storage boxes, food containers, tableware, plastic basins, buckets and other household items, meeting the daily use needs of consumers.

Automotive Industry

It can be applied to automotive interior decorative parts, such as dashboard decorative panels, door handle bases, glove box shells, seat decorative covers, etc. Due to its good rigidity and appearance quality, it provides lightweight and durable solutions for automobiles, helping to improve fuel efficiency while meeting the appearance and performance requirements of automotive interior parts.

Home Appliance Industry

In the home appliance industry, it is used for manufacturing home appliance shells and internal structural parts, such as TV back covers, air conditioner external unit decorative panels, washing machine internal components, small household appliance shells, etc. Its good dimensional stability and rigidity ensure the assembly precision and service life of home appliances.

Electronics Industry

Taking advantage of its good electrical insulation properties and dimensional stability, it can be used for making ordinary electronic insulation parts and plastic shells, such as power supply shells, charger casings, electronic product packaging trays, etc., providing reliable material support for the electronics industry.

Processing & Storage Guidelines

Processing Parameters

Temperature: The recommended processing temperature for injection molding is between 180 - 225°C (feeding section: 180-190°C, compression section: 200-210°C, metering section: 210-220°C, nozzle: 210-225°C).

Ratio: When blending with additives such as color masterbatch and antioxidant, the appropriate material-to-additive ratio should be determined according to the specific application requirements, generally 95:5 (material:additive) for reference, and small-batch test runs are recommended before mass production.

Drying requirements: The product has extremely low moisture absorption (less than 0.01%). If stored in a sealed and dry environment, pre-drying is not required before processing. If the pellets are damp due to improper storage, they can be dried at 60-70°C for 1-2 hours, and then cooled to room temperature before processing to avoid material degradation and yellowing.

Storage Requirements

Temperature: Store in a cool and dry warehouse, with a storage temperature range of 5 - 30°C.

Humidity: Keep the relative humidity below 60% to prevent the pellets from absorbing moisture and affecting processing performance.

Stacking limits: Do not stack more than 5 layers to avoid deformation of the packaging bags and compaction of the pellets, which will affect the feeding during processing.

Shelf life: The product has a shelf life of 2 years when stored under the above proper conditions. It is recommended to follow the "first-in, first-out" principle for use to ensure the stability of the material performance.

Other requirements: Keep away from direct sunlight, heat sources, open flames and strong organic solvents during storage; ensure the packaging bags are intact to prevent the pellets from being contaminated by impurities.

Frequently Asked Questions 

Q1: What is the maximum operating temperature of the Yanchang V30G?

A: The long-term safe operating temperature of Yanchang V30G is below 80°C, and its heat deflection temperature (0.45MPa) is 88°C. Beyond 88°C, its performance may start to degrade, such as softening and deformation. Short-term exposure to temperatures below 100°C may be acceptable, but it is not recommended for long-term use in high-temperature environments.

Q2: Can the Yanchang V30G be recycled?

A: Yes, it can be recycled. As a polypropylene material, Yanchang V30G has good recyclability, which is in line with environmental protection requirements. Waste products produced during production can be recycled and granulated for reuse after cleaning and drying. Recycling can also reduce production costs and resource waste, but it should be noted that the mechanical properties of recycled materials will decrease to a certain extent, and they are not suitable for products with high performance requirements.

Q3: How long does it take to process the Yanchang V30G?

A: The processing time depends on the specific processing method, equipment type and product structure complexity. Generally, for ordinary injection molding products such as daily necessities and small automotive interior parts, the injection molding cycle takes about 10 - 15 minutes. For products with complex structures or large sizes, the processing time will be appropriately extended, and specific parameters need to be adjusted according to actual production conditions.

Q4: Is the Yanchang V30G suitable for outdoor use?

A: The original Yanchang V30G does not contain UV stabilizers and has poor weather resistance, so it is not suitable for long-term outdoor use (more than 3 months). Long-term exposure to direct sunlight and extreme weather conditions will cause the material to age, yellow and become brittle, affecting the service life of the product. If it is necessary to use it outdoors for a short time, it is recommended to add UV masterbatch during processing to improve its weather resistance.

Q5: What is the warranty period of the Yanchang V30G?

A: The warranty period is 1 year from the date of delivery. During this period, if the product has quality problems such as unqualified performance parameters or impurities in the pellets due to the manufacturer’s production reasons, the manufacturer will provide free replacement services after verification. It should be noted that the warranty does not cover quality problems caused by improper storage, incorrect processing parameters or improper use by the buyer.
