2021 High quality Pu Outsole Mould Maker - PU Mould – Xieli

Product Details

A few decades ago, the footwear industry was searching for an alternative to the conventional sole materials to create a more robust, stylish and sustainable sole. The quest saw a new hope when the sole manufacturers had caused a disruption with an intriguing and innovative material – Polyurethane (PU).
The PU sole manufacturers have been endorsing and providing this splendid sole material for several years to create a plethora of footwear. The primary reason for its popularity is that the PU sole advantages the footwear manufacturers as well as the end users to a great extent with its amazing properties.
The polyurethane has been extensively utilized as a shoe sole material to develop robust and sustainable high-quality shoes for the applications requiring rough use such as trekking, sports, labour-intensive industries, etc. However, the PU sole manufacturers have made it possible now for them to be used as a sole material for causal and office footwear like formal shoes, sport shoes, safety shoes, sandals, sneakers, chappals etc. Moreover, the constant endeavours of the PU sole manufacturers and the continual demand for this material by the footwear industry, have now made the polyurethane quite affordable. The reasonable cost of the PU sole makes it suitable to be used in more types of footwear than its conventional counterparts.
1. Performance advantages of PU sole stock solution
Polyurethane sole has the characteristics of lightness, warmth, oil resistance, flexural resistance, and abrasion resistance, which is 6 times more abrasion-resistant than rubber. According to needs, it can be made into two-color (dual-density) double-layer shoe soles, the lower sole is a micro-foamed high wear-resistant working surface, and the inner sole is a comfortable elastic foam.
Extremely light, with a specific gravity of only 0.3-0.8, which is much lighter than commonly used sole materials, and is more suitable for thick-soled shoes that require impact resistance and perforation resistance.
The mold requirement is low, and the production is convenient and the investment is saved (the pressure on the mold is small during foaming, only 0.14-0.20MPa).
2. Composition of PU sole stock solution
PU sole stock solution can be divided into polyester type and polyether type.
Polyester type: prepolymer method and semi-prepolymer method are mostly used, generally composed of three components A, B, and C. The components of each component are as follows.
Polyether type: more one-step method is adopted, component A is directly prepared by fully mixing polyether polyol, catalyst, blowing agent, foam leveling agent, chain extender, etc. in a mixer, component B is modified isocyanate Or liquefied MDI.
The molding method is simple, and it can produce both soles and continuous shoes. Variety and output are flexible and suitable for modern industrial production.
