Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.

—— Short supply of ethylene propylene rubber in the market The only domestic Jilin Petrochemical can produce ternary, binary and other grades, 80% of which need to be imported from abroad. At present, there are two main reasons for the shortage of goods in the market: First, due to the Spring Festival holiday, part of the ethylene-propylene rubber shipping schedule is postponed. In February, the supply of goods to Hong Kong is limited and the market supply is reduced. Second, it is heard that Dupont's EP equipment has been suspended for overhaul maintenance. The supply volume in the first quarter has been reduced, and the Dutch DSM ethylene unit has also experienced problems. The recent market supply is extremely scarce. And Japan's Sumitomo, the United States lion's chemical OEM is in a very high position, the domestic agents rarely have access. Since most of the foreign suppliers prefer Europe and reduce Asian supplies, the tight supply situation in the Chinese market will not be eased.
- The external disk continues to rise as most products need to be imported from abroad. China's ethylene propylene rubber market has always been to look at foreign suppliers "face." At present, the price of foreign ethylene-propylene rubber is at a high level, and the increase is unabated. The market prices of various brands produced by DSM in the Netherlands are sharply consolidating, with an increase of up to 5,000 yuan. The recent supply of new goods is tight and the price continues to rise. It has now reached more than 42,000 yuan; Dow, DuPont, LANXESS, and Japanese products also stand Above the 43,000 yuan high. Kumho KEP products 330, 350, 210 and other brands in the price between 4300 ~ 45000 yuan.
——Commercial stocks are expected to rise As optimistic about the market of ethylene-propylene-propylene rubber, domestic traders have hoarded goods and relied on the attitude of reluctant sellers to further push up market conditions. In addition, prices of downstream products, such as tires, have all been adjusted upwards. Michelin and other tire giants have announced price increases, with price increases ranging from 5% to 10%, which is also a favorable factor for the ethylene propylene rubber market.
However, the ethylene propylene rubber market has also some negative factors: First, high rubber prices, lower production costs of downstream factories, some manufacturers operating rate decreased, receiving goods cautious; Second, by the spring and other factors, car sales may decline; National preferential policies, such as stopping the reduction of auto purchase tax policy, the central bank raising interest rates, etc., can not be overlooked in the impact of ethylene propylene rubber downstream companies.
In summary, the supply of ethylene propylene rubber is in short supply, and the attitude of reluctant sellers is relatively strong. The phenomenon of market price-free and non-market is becoming more prominent. Manufacturers mainly rely on direct supply of downstream factories, and the situation in which purchasers are somewhat difficult to purchase is difficult to change in the short term. After the ethylene propylene rubber market still has room to rise. However, as the price of ethylene propylene rubber continues to set a new record high, the market risk is also increasing.
Ethylene-propylene rubber follows 40,000 yuan high point on natural rubber station
Sinochem New Reuters reported that natural rubber prices stand at a high price of 40,000 yuan (t price, the same below), and ethylene propylene rubber is not unwilling to be lonely, followed by breaking the 40,000 yuan mark. Ethylene-propylene rubber prices have soared since late February, breaking the 40,000 yuan mark in one fell swoop, and the mainstream quotation for conventional brands reached a high of 41,000 to 44,000 yuan, an increase of 5,000 yuan or more, and both prices and gains hit a record high. After the price of Jilin Petrochemical's 4045 exceeded 40000 yuan, the price continued to rise. The quotation for the last weekend had risen to 450 million yuan. The main driving force for this hot market is the tight market supply and the continued increase in offer. If there is no obvious change in these factors, it will continue to push up the market for ethylene propylene rubber, and prices will continue to break new heights.
