Q1: What is a modified polymer material?
A: Modified polymer materials are produced by adding glass fibers, flame retardants, toughening agents, colorants, and other additives to basic plastic raw materials (such as PC, ABS, PP, etc.). Through blending and extrusion granulation, the original physical properties of the raw materials are altered to achieve special properties such as flame retardancy, toughening, anti-static properties, weather resistance, and low odor, meeting the requirements for use in electronic, home appliance, packaging, and other products.
Q2: What material customization services can Yunhe Polymers provide?
A: Dongguan Yunhe Polymers provides customized formulations for modified plastics such as PC, PC/ABS, and PP, with adjustable impact strength, flame retardant grade, color, low odor, and temperature resistance. We offer sample analysis, formula development, prototype testing, and production, supplying from small to large batches. Additionally, we provide supporting plastic raw materials, color powders, and additives, and support import and export business.
Q3: How long is the sample making cycle for modified plastics?
A: For regular colors and general modified formulas, samples are generally provided within 3~5 working days; for special flame retardant, low VOC, and high weather resistance customized formulas, it takes 7~10 days. After the sample is completed, physical property testing data will be provided to facilitate customer injection molding testing.
Q4: Can modified materials be used for food contact or electronic casings?
A: Yes, we can customize corresponding formulas based on the usage scenario. Electronic enclosures can be modified for flame retardancy and anti-static properties; for food contact scenarios, raw material systems that meet corresponding standards need to be selected. Before placing an order, you can inform us of the usage environment, and Yunhe Polymers will match a compliant raw material solution.
Q5: When purchasing modified plastics, how can one judge whether the material quality is good or not?
A: The focus is on four key points: ① stability of color and melt index across batches; ② compliance with physical property indicators such as impact strength and tensile strength; ③ particles free of black spots, burnt particles, and dust; ④ uniform dispersion of additives, with injection molding less prone to defects such as water spray and peeling. Each batch of Yunhe polymer products comes with a reserved sample for testing, facilitating customer re-inspection.
