PVC Compound Granules for Shoe Soles

At Chihao we produce PVC compound granules for shoe soles, a raw material made from PVC resin and a set of plastic additives. The granules are supplied in virgin and recycled grades, in white, gray, black and transparent colours, and the grade is chosen by density, hardness and the part being moulded. Our factory in Xiamen, Fujian, also produces PVC plasticizers, flame retardants and titanium dioxide, so a customer can source the compound and the additives from one supplier. The product is packed in 25 kg bags and is used for soles, uppers and other moulded parts. The granules are sold by grade rather than by a single universal specification, so the application and the process should be stated at the enquiry.

Grades and Properties

The table of grades shows virgin PVC granules at densities of 1.25, 1.27 and 1.30 with hardness values of 60, 65 and 65, and recycled granules at densities of 1.47, 1.30 and 1.41 with hardness of 75, 65 and 70. The application for all of these grades is shoes, soles and uppers. Density and hardness are the first two figures a buyer should compare, because they affect the weight and the feel of the finished sole. The compound is described as resistant to ageing, high and low temperatures, weather and UV, and it carries a flame retardant rating and chemical resistance for demanding applications.

Colour and Customization

The standard colours are white, gray, black and transparent, and custom colours are available. The grades cover customized automotive parts, universal grades and pipe grades, so the same production line can serve a shoe sole, an automotive interior part and a pipe fitting with different formulations. A buyer should send the colour reference, the hardness target and the application, and we will confirm which grade fits. Where a part is visible, a colour sample or a trial batch is the safest way to approve the match before a full order. If a colour is critical, send a physical sample as well as a code, because a screen image cannot show the final tone.

Packing and Storage

The compound is packed in 25 kg bags with PE packaging. Bags should be stored in a dry, shaded place, away from direct sunlight and heat, and the stock should be used in rotation. PVC compound is not a food product, but it should still be kept clean and free of contamination, because dust and moisture can affect the moulding result. For export, the pallet plan and the bag printing should be confirmed with the order, since different markets have different labelling requirements. For repeat orders, keep the same grade and colour reference, because a small change can change the feel of the finished sole.

Where the Granules Are Used

The main use is footwear: soles, uppers and other moulded parts, including foamed soles for automobile interiors. The compound can also be used for pipe fittings, electrical parts and general moulded products when the grade is matched to the requirement. Because the same material name can cover a wide range of formulations, the buyer should state the process, the hardness, the colour and the end use rather than ordering by name alone. We will explain the difference between the grades in plain terms and confirm what is available.

Working With Chihao

Fujian Chihao New Materials Co., Ltd. is based at Room 220, No. 368 Jinyin Road, Tong'an District, Xiamen, Fujian, China. We specialize in biomass PVC plasticizers and PVC granules, including chloromethyl fatty acid ester plasticizers used in PVC disposable medical consumables, leather products, children's toys and polyurethane-related materials. For the PVC compound granules for shoe soles, contact us on 0086-13850085201 or at julias@plasticizerpvc.com with the grade, colour, quantity and destination, and our team will reply with the options and the next steps.

We also supply DOP, DINP and DOTP plasticizers, flame retardants and titanium dioxide, so a compound buyer can discuss the additive package at the same time as the granules. If you are comparing suppliers, ask for the density, the hardness, the colour and the packing in writing, and compare them on the same basis. Our sales team will tell you clearly which items are standard and which need a custom formulation.
