Poly(acrylic acid) (PAA; trade name Carbomer or Carbopol) is a polymer with the formula (CH2-CHCO2H)n. It is a derivative of acrylic acid (CH2=CHCO2H). In addition to the homopolymers, a variety of copolymers and crosslinked polymers, and partially deprotonated derivatives thereof are known and of commercial value. In a water solution at neutral pH, Carbopol 940 is an anionic polymer, i.e., many of the side chains of PAA lose their protons and acquire a negative charge. Partially or wholly deprotonated PAAs are polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume. These Sodium Hexametaphosphate properties - acid-base and water-attracting - are the bases of many applications.
Carbomer940 Carbopol is a polyolefin. It can be viewed as polyethylene Titanium Dioxide with carboxylic acid (CO2H) substituents on alternating carbons. Owing to these groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral). For this reason, Carbopol 340 Tinci Carbomer exists in atactic, syndiotactic, and isotactic forms, although Carbopol 940 Price this aspect is rarely discussed. The polymerization is initiated with radicals and Carbopol Powder is assumed to be stereorandom. Crosslinking can be introduced in many ways.

The lighting industry usually has a close relationship with the property market. The prosperity and fading of the property market directly affects the prosperity of the lighting market. This year, the property market restrictions on the purchase of a wave of waves, directly affecting the sales of the lighting industry. The CPI continued to rise and the country's monetary tightening brought a hard impact to the hardware and lighting industry, which also dragged down the development of the industry.
It is understood that in the first half of 2011, the hardware lighting market was cold and the passenger flow was scarce. The sales of the whole industry plummeted, the profit margin continued to shrink, forming a cold winter trend, and the business operation was very difficult. The group heating could help the company to survive the winter. Win the life.
The group is a very popular word in the industry now, and it represents the development trend of an industry. When the hardware lighting industry is experiencing a cold winter, the combination of enterprises may bring a glimmer of life.
The combination of enterprises is mainly in three aspects:
1. External joint efforts to jointly resist foreign investment and seize the Chinese market;
Second, the sharing of resources, when the cost is high, complementary or can produce unexpected results;
Third, the sharing of technology, high technology can always bring a strong appeal to the product, technology sharing, can bring innovation to the hardware lighting products.
