Hot melt adhesive for shoes refers to a general term for a class of hot melt adhesive products used in the field of shoe processing, which is not a single model of hot melt adhesive film products. Due to the diversity of shoe-making materials, there are many types of hot melt adhesives used in the field of shoe materials. To make a simple summary, the common types of tpu hot melt film with low temperature release film, and the types of pa and tpu hot melt omens.
So, what are the characteristics of using hot melt adhesive as a adhesive for shoe materials compared with traditional white glue and yellow glue? The characteristics of hot melt adhesive for shoes compared with traditional shoe adhesive are mainly in the following aspects: Hot Melt Adhesive For Shoe,Non-Slip Socks Hot Melt Glue,Non-Slip Pressure Sensitive Adhesive,Non-Slip Adhesive For Socks Shenzhen Tongde New Materials Technology Co., Ltd. , https://www.tdhotmeltglue.com
1, more environmentally friendly than traditional adhesives, both for the production of operators, or consumers are more healthy;
2, better air permeability: especially for shoes with high air permeability requirements, the air permeability of hot melt adhesive will be better than traditional adhesives;
3, better bonding strength: from the perspective of the composite effect, the bonding strength of hot melt adhesive is better than that of traditional glue;
4, from the production point of view: hot melt adhesive is easy to continuous operation, can greatly increase the production efficiency of the enterprise.
Dimethyl ether is used in town gas for competitiveness>
At the 2007 China DME Production, Application, and Technology Exchange Conference held in Zhangjiagang City, Jiangsu Province, on December 13–14, experts from across the country discussed the potential of dimethyl ether (DME) as a viable urban gas alternative. They concluded that DME not only matches but outperforms traditional fuels like liquefied petroleum gas (LPG) in both performance and cost-effectiveness, making it highly competitive in the market.
Currently, China’s urban gas supply mainly relies on LPG, coke oven gas, and natural gas. However, the development of coke oven gas has slowed down in recent years, while LPG consumption continues to rise. As of now, China ranks third globally in LPG consumption, with imports accounting for about 30% of total usage—second only to other major importers. In the first quarter of 2007 alone, LPG imports reached 1.708 million tons, marking a 48.7% increase compared to the same period in 2006.
With limited natural gas resources, China is expected to face a supply gap of 20 billion cubic meters by 2010. The Mid-term Plan for Urban Natural Gas Utilization (2006–2010) projected a demand of 41.377 billion cubic meters by that year. Given the rising global energy prices and increasing reliance on imports, it's clear that long-term solutions must come from domestic alternatives.
The upcoming "Dimethyl Ether for Town Gas" standard in China will grant DME legal status as an alternative fuel, paving the way for its broader adoption. According to Chen Weiguo, Secretary-General of the National Alcohol Ether Fuel and Alcohol Ether Clean Automobile Professional Committee, DME has a higher calorific value than LPG, with a premixed gas value of 4,219 kJ/m³ compared to LPG’s 3,909 kJ/m³. Additionally, DME operates at a lower pressure (1.35 MPa vs. 1.92 MPa for LPG), has a higher lower explosion limit (3.5% vs. 1.7%), and is safer for storage and transportation.
Testing results also show that DME stoves perform exceptionally well, with a 100% ignition rate and a stable flame. With LPG prices currently exceeding 5,000 yuan per ton—sometimes reaching 7,000 yuan—DME, priced around 3,300 yuan per ton, offers a much more economical option.
Huang Zhen, Dean of the Energy Research Institute at Shanghai Jiao Tong University, noted that as oil and natural gas prices remain closely linked, and with the eventual introduction of fuel taxes, DME’s economic appeal is set to grow even further. He also mentioned that future improvements in production technology could reduce costs and energy consumption, making DME even more attractive.
In practical terms, one ton of DME can provide cooking fuel for five families over five years, and it’s suitable for rural areas without natural gas infrastructure. A 400,000-ton-per-year production facility could serve 8 million people annually. By 2010, if 20% of LPG is replaced by DME, the demand would reach 6 million tons, signaling a massive market opportunity for this clean and efficient fuel.
