Haptex was discovered as an innovative PU solution for the production of synthetic leather after discovering an unique method of elimination of the wet line in the production of synthetic leather – something that conventional manufacturing systems cannot do without.
Why Haptex is different from any other synthetics
Haptex produces 52% less carbon emissions that conventional synthetic leather, with more than 20% reduction in energy consumption when using 1KG of chemicals for synthetic leather production. This is predominantly due to the elimination of the wet line from production processes which reduces 30% of water usage compared to usual solvent-based PU production methods. Haptex in addition does not use any organo tin catalysts or plasticizer. These results are highlighted in a recent LCA (Life Cycle Assessment) study commissioned by BASF.
Enhanced with a higher peel strength, anti-yellowing, and high abrasion performance properties, Haptex enables great performance. In collaboration with Warren Synthetic Leather (Suzhou) Co., Ltd and Suzhou Greentech Co., Ltd , the product is further enhanced for higher performance and at the same time ensures that it meets stringent VOC standards with zero solvents and extreme low levels of VOC emission; enabling it to be a sustainable artifical leather solution.
Haptex enables designers to achieve high performance and the desired appearance of applications using synthetic leather across different industries, such as furniture, footwear, automotive, apparel, and accessories.
Fusing style and functionality in apparel and footwear
Leather for the footwear and fashion industry must be adaptable to allow a range of material treatments that result in textured and tumbled finishes for different designs. Thanks to Haptex, the highly versatile material can meet these requirements as well as satisfy the growing customer demand for sustainable leather. Brown shoes made with Haptex have a soft and supple feel, bringing comfort and fashion together. Its new high adhesive base also enables long-lasting footwear.
Haptex was recently used in a concept shoe – X-Swift created by BASF together with footwear designer Gu Guoyi. The shoe was entirely made up of BASF materials and featured at Asia’s largest plastic fair – Chinaplast in 2019.
It was also featured in Limitless – safety concept shoe that is also entirely made up of BASF materials. To realize the vision of a safety shoe without laces, a knitted upper made from Freeflex® fiber is combined with a protective overlay made from Haptex®, BASF’s premium solvent-free artificial leather. The durability of the material and versatility to adhere to a variety of shoe adhesives made this vision possible.
Benefits in production costs
The elimination of the wet line process has significantly brought down the cost of synthetic leather production. Results from the LCA study prove that the expected carbon emissions from Haptex along with its production processes and life cycle represent a very appealing alternative for products that require synthetic leather in everyday products especially where people are constantly exposed to such as automotive seatings, furniture, footwear and fashion accessories like bags and caps.
Benefits to use Infinergy in conjunction with Haptex
While Haptex can be used as part of the shoe upper, Infinergy – the World’s leading high performance responsive material can be used as insoles or as part of the sole core for better comfort and energy return.
This enables professionals who constantly need to be on the move or on their feet to feel less fatigue and more comfort.
