Honeywell lubricant additives help PVC stabilizers go the extra mile

Chongqing Taiyue selected Honeywell lubricant additives to create an environmentally friendly PVC stabilizer

After Chongqing Taiyue introduced Honeywell's high-performance anti-precipitation lubricating additives into the environmentally friendly calcium-zinc stabilizers produced, it effectively improved the problems of short mold cleaning cycle, insufficient thermal stability, poor gloss, serious precipitation and narrow processing window in the processing process of PVC materials, improved the production stability and improved the key physical properties of PVC products, and promoted the conversion process of the PVC industry from lead salt stabilizers to environmentally friendly calcium-zinc stabilizers.

Outline:

Chongqing Taiyue Technology Co., Ltd. (hereinafter referred to as "Chongqing Taiyue") is committed to promoting the conversion process of the polyvinyl chloride (PVC) industry from lead salt stabilizers to environmentally friendly calcium and zinc stabilizers. After the introduction of Honeywell's high-performance anti-precipitation lubricating additives into the environmentally friendly calcium and zinc stabilizers produced by the company, it has effectively improved the problems of short mold cleaning cycle, insufficient thermal stability, poor gloss, serious precipitation and narrow processing window in the processing process of PVC materials, and at the same time improved the production stability and improved the key physical properties such as tensile strength and impact strength of PVC products, thereby helping Chongqing Taiyue and its downstream PVC producers to get out of the fierce market competition. A high-quality differentiation path.

Background:

As a major supplier of new high-efficiency and environmentally friendly calcium and zinc heat stabilizers for PVC in southwest China, Chongqing Taiyue has been actively promoting the conversion process of the PVC industry from toxic and harmful lead salt stabilizers to environmentally friendly calcium and zinc stabilizers.

Traditional PVC stabilizers are mainly lead salt systems, and although they have excellent performance, they have been gradually banned or restricted by many industries due to their lead content. As early as 2000, many countries in Europe began to ban lead salt stabilizers in PVC, and by 2015 the use of lead salt stabilizers had been banned by 100%.

As early as 2003, China kicked off a comprehensive ban on lead in PVC plastic products. The new national standard GB/T 10002.1-2006, which came into effect on August 1, 2006, indicates that PVC pipes for water supply must be "produced as non-lead salt stabilizers". In 2016, the Ministry of Housing and Urban-Rural Development officially issued the "Industry Standard for High-performance Polyoxyethylene Pipes and Connectors for Water Supply" (CJ/T493-2016), requiring that "lead salt stabilizers should not be used in PVC-UH pipes". However, in addition to drinking water pipes, in other applications of PVC, China's lead ban action has not been fully launched, the corresponding standards have not been introduced, and the lead ban campaign still has a long way to go.

The reason for the resistance to banning lead is not unrelated to the technical obstacles. Although a variety of lead-free stabilizers have appeared on the market many years ago, they have never been able to compare with lead salt stabilizers in terms of performance and cost, which is also a technical problem that has plagued stabilizer manufacturers and PVC product companies for many years.

Take ordinary calcium-zinc stabilizers as an example. Short mold cleaning cycle. Thermal stability is not enough. Poor gloss. Problems such as serious precipitation and narrow processing window directly affect the production process and product quality of PVC profiles and pipes, which not only have high production costs, but also lead to high waste products, unstable product quality, and difficult to meet the requirements of product performance. PVC products using calcium-zinc stabilizers generally have tensile strength. Outstanding quality problems such as poor surface gloss and easy frosting have undoubtedly set up a big resistance to the environmental protection process of the PVC industry.

Solution:

Despite the obstacles, Chongqing Taiyue has been tirelessly looking for solutions to improve the performance of calcium and zinc stabilizers. Honeywell, as the world's first commercial manufacturer of low molecular weight polyolefin polymers, was the partner of choice for Chongqing Taiyue in this environmentally and economically beneficial project.

Honeywell PVC specialty lubricants include paraffin. Chemical products such as hydrocarbon-based waxes, fatty acid esters and amides, special stearates, oxidized and non-oxidized low-molecular-weight polyethylene.

For half a century, Honeywell A-CI high-performance additives have been recognized by manufacturers around the world; For nearly 30 years, the more innovative Rheochem PVC lubricants have established themselves as the world's leading brand in the rigid PVC industry for custom wax blends. Especially in the calcium-zinc system, A-C* and Rheachem "have been successfully used for many years and show their superior plasticizing ability, which can make the parts gloss higher and better performance.
