HNBR

Unlike NBR, hydrogenated NBR elastomer has high heat and ageing resistance, which means that it is frequently

used both in sealing technology and also in dynamically challenging applications. In long-term operation , fully

hydrogenated HNBR grades can withstand temperatures of up to 150°C. Partially hydrogenated HNBR can be

crosslinked both with sulfur and accelerators and with peroxides, whereas fully hydrogenated HNBR can only be

crosslinked with peroxides.

Hydrogenated NBR elastomer – advantages at a glance:

• Good media resistance/chemical resistance
• High mechanical and dynamic strength
• Suitable for use with hot water and steam
• Ozone and weathering resistance
• Good low-temperature flexibility
• Low compression set
• High ageing resistance
• Thermal stability from -40 to +150°C

Weihai New Era Chemical Co., Ltd. is a private company specialising in the development and manufacture of fluorosilicone rubber. The product range of fluorosilicones includes monomers, polymers and compounds.

The quality was successfully certified according to ISO 9001, ISO 14001 and ISO 18001.

Fluorosilicone rubber has its main application in seals, diaphragms and O-rings for the automotive industry. Other applications include coatings for chemical-resistant textiles. An advantage over silicone rubber is the good resistance in oil and fuels. The possible application temperature of fluorosilicone is wide. The material can have a low-temperature resistance of minus 50 °C up to a heat resistance of well over 200 °C, special types up to 300 °C. The material can also be used for a wide range of applications.

The current product range comprises a total of 4 product groups with 10 different individual products:

NFS 9100 – Series         Universal types

NFS 9200 – Series         High tear and tear propagation strength

NFS 9300 – Series         Low compression set

NFS 9400 – Series         Good rebound elasticity

Zhonghao Chenguang Research Institute of Chemical Industry has become the largest and leading manufacturer of fluorochemical products in China since its foundation in 1965. Starting with fluorspar, all required monomers and precursors such as HF, HFP, TFE, VDP and Freon are produced in-house.

With more than 400 developers, the company is also involved in the Chinese government’s Aero Space program.

In addition to the largest Chinese production facility for water-soluble PTFE dispersions, a further plant with an annual capacity of 18,000 metric tons is in operation:

In Ajka (Hungary), MAL produced 35,000 million tonnes of ground aluminium trihydrate called Alolt in various grain sizes.

The powder material is available in paper bags on pallets, big bags as well as in silo trains.

In the course of the relocation of production from precipitated ATH to IC Profil in Zvornik (Bosnia), initially only the 4 m² material is produced under the name Alolt 60 DLS. The availability is specified in silo trains or Big Bags. From 2020, the start of production of 7 m² material Alolt 90 DLS as well as 10 m² material Alot 120 F is planned.

Overall, the capacity of precipitated ATH in Bosnia, after completion of all investments, is expected to reach 50.1 Million tonnes.

As a result of continuous further development, silica can be offered in various compositions and settings for use in the rubber industry. The variety of types is constantly being expanded – also for other branches of industry and applications.

Precipitated silicic acid Ebrosil

Precipitated silica is the synthetic form of amorphous white silicon dioxide and has the same chemical composition as sand: SiO2. The properties of this material are determined by parameters such as particle size distribution, porosity, surface area and purity. This synthetic material is used in a variety of applications and is indispensable in areas such as the pharmaceutical industry and ecological tire manufacturing.

Aluminium silicates Ebrosil SA 60

With the increasing demand of the production industry for alternative – and in some respects also more effective – whiteners, additives, the development of silicates began and displaced the previously predominant position of titanium dioxide. Since then, the industrial interest in this type of filling materials has not diminished and silicates have become indispensable in a wide variety of applications, such as whiteners in the manufacture of paints and printing inks, or as raw material in the rubber and paper industries.

MIKROFINE® OBSH is an exothermic chemical blowing agent that is widely used in a lower temperature range from about 150 to 160 °C. It is used for the production of a wide range of products. It is an efficient, odourless, non-discolouring and non-toxic nitrogen-releasing blowing agent for use in natural and synthetic sponge rubber as well as expanded plastics. MIKROFINE® OBSH does not produce ammonia and is therefore safe for the insulation of cell cables.

MIKROFINE TSH is a chemical blowing agent for expanded rubbers which are processed in the temperature range 120-160 °C. It is used for the production of rubber compounds in the following applications
