Covestro becomes majority stakeholder in DIC Covestro Polymer joint venture in Japan

The difference between fireproof cloth and silicone cloth

Covestro accelerates the expansion of its Thermoplastic Polyurethanes business (TPU) by raising its stake in the Joint Venture DIC Covestro Polymer Ltd. (DCP) from 50 to 80%. DCP, established as a 50/50 joint venture in the year 2000, is a leading company in the Japanese TPU industry. The investment is part of Covestro’s expansion of its global TPU business. The total investment sums up to a low double digit million EUR. Both parties agreed to not disclose any further financial details of the transaction. Closing of the deal is planned for early second quarter 2019, subject to the approval from the relevant authority.

“The strong and long-term partnership of both companies, as well as our thorough understanding of the future growth potential make this acquisition a fitting step in Covestro’s growth strategy focusing on sustainability driven innovation”, said Dr. Markus Steilemann, CEO of Covestro.

Covestro is a leading supplier of high-performance resins and globally a top 3 producer of TPU. The TPU business is part of the Coatings, Adhesives, Specialties (CAS) segment and accounted for approximately 10% of the segment sales in FY 2017. The global TPU industry is estimated to grow at a long-term average of 6% p.a., while Covestro outgrew the industry with double-digit core volume growth per year in the past three years.

Continued partnership, unique product and R&D capabilities

DIC Corporation (DIC) will continue to support the success of DCP with its industry network, strong brand name, and as a reliable local partner. Production and R&D by DCP will continue at Sakai plant located in the DIC facility in Sakai, Osaka Prefecture, getting support from DIC such as supplying feedstocks and providing services on site. DIC is also an important partner for Covestro in other Coatings, Adhesives and Specialties business. The acquisition complements Covestro’s recent organic global capacity expansions of TPU sites in New Martinsville (USA) and Changhua (Taiwan), which raises the respective annual TPU production capacities by approximately 25% each.

“DCP’s unique local capabilities together with Covestro’s global network will form a powerful combination going forward. The differentiated product portfolio fits well into our pursuit to grow in more resilient, profitable businesses,” says Kimiyasu Yonemaru, President of Covestro Japan. “It shows a clear commitment from Covestro to the Japanese market.”

How to choose good fireproof silicone cloth?

1. Confirm what our real needs are, especially the temperature requirements;

Pay attention to the thickness while choosing fireproof silicone cloth. Under the same temperature condition, different thickness, the different parameters of temperature deformation will be. Generally speaking, for thicker silicone cloth, the shape is more stable.

3. Strength, some clients use it for equipment which requires wear resistance.

The difference between fireproof cloth and silicone cloth

The difference between fireproof cloth and silicone cloth

The fireproof cloth is mainly made of fireproof and non-combustible fiber and processed by special process. Main features: non-combustible, high temperature resistance (550~1100℃), compact structure, non-irritating, soft texture, easy to wrap objects and equipment with uneven surface. The fireproof cloth protects the object away from the hot and spark zones and completely prevents combustion or isolation.

Silicone cloth is made of two main raw materials. It is made of glass fiber cloth with high strength and high temperature resistance. It is compounded with silicone rubber and vulcanized at high temperature.

The fireproof cloth is suitable for use in places with spark such as welding, and it is prone to fire. It can withstand spark splashing, slag, welding spatter, etc., to isolate the working place, separate the working layer, and prevent the fire hazard that may be caused during the welding work; It can also be used as a light barrier to create a safe, clean and standardized working space.

Fireproof cloth is the ideal protection tool for fire safety. When it is used for construction in public places such as large shopping malls, supermarkets, hotels, etc., such as welding, cutting, etc.: using fire blanket can directly reduce spark splash and play flammable, Isolation and blocking of explosives.

Fireproof cloth is widely used in the shipbuilding industry for the construction and repair of the ship frame; it can also be used in places where the petrochemical enterprises are insulated from metal structures and need to be welded, showing good protection and adaptability.

The characteristics of high-quality high termperature silicone cloth

The characteristics of high-quality high termperature silicone cloth.

Compared with normal single-sided silicone cloth and double-sided silicone cloth, high-temperature silicone cloth should have the following characteristics:

1. Low temperature/high temperature resistance.

High quality alkali-free fiberglass base fabric which ensures long-term operation temperature at 550℃. If special 316# stainless steel wire reinforced glass fiber base fabric is used, it can work for a long time at 1000℃. In addition, the excellent silicone rubber mixing process can make the silicone cloth have better high temperature stability, and it will burn-in and crack even when burning.

High quality silicone cloth also has excellent low temperature resistance. It still has good elasticity in a low temperature environment of -50℃.

Because of its excellent high/low temperature resistance, high temperature silicone cloth is widely used in various high temperature insulation protection and low temperature insulation projects.

2. Excellent weather resistance, aging resistance, waterproof / water vapor, chemical resistance.

3. The high-quality silicone rubber vulcanization process makes the silicone cloth have higher weathering and aging resistance. Whether it is direct sunlight, rain erosion, extreme weather conditions, or ordinary acid-alkaline corrosion conditions, high-quality high-temperature silicone cloth can ensure service life of more than 10 years.

3. High strength, good air tightness.

Excellent silicone rubber compound with relatively high density and uniform dispersion. The silicone cloth has excellent airtightness and is excellent to provent erosion of water, steam and other chemical solvents. At the same time, the excellent tear strength can prevent the surface from being scratched or pierced by sharp objects, which effectively protect the target object.

4. Good elasticity, easy to cut and sew.

For high-quality silicone cloth, it is easy to cut, no loose edges after cutting, no hairiness and easy to suture. Meanwhile, the excellent fabric elasticity after sewing.

The surface is flat, the colors are diverse, and it is easy to classify.

The excellent coating process ensures that the silicone cloth has a smooth surface, uniform color and good rubber fastness. High quality silicone cloth is available in a variety of colors. Whether it is a designated color that identifies the characteristics of the user’s business, or a special warning color, the diversity of colors is more conducive to the differentiation and management of materials and uses.
