Frequently Asked Questions (FAQ)
A1: Our compounds are suitable for compression molding and are available in both powder and granular forms to meet various processing requirements.
A2: Yes, Runtai provides professional customized color matching services. You can provide a Pantone color card number or physical color samples for us to match.
A3: Urea Moulding Compound is highly preferred for tableware and dinnerware because of its excellent durability, heat resistance, and ability to support vibrant colors and detailed designs.
A4: It must be stored in a cool, dry, and well-ventilated room with temperatures not exceeding 25°C. Avoid exposure to heat, moisture, contaminants, or physical packaging damage during transit and storage.
A5: The standard shelf life under recommended storage conditions is six months. If the period is exceeded, the compound can still be used if it passes inspection based on product technical standards.
A6: We offer flexible packing solutions, with product availability in 20kg, 25kg, and 1000kg plastic woven bags.
