Rubber Compound Nitrile/PVC

Compounds made from Nitrile rubber and PVC have excellent physical and chemical properties, that is why it has got maximum share in Printing applications properties of Nitrile get enhanced with straight PVC, there by excellent properties can be availed for different applications over nitrile only.

Smooth finish after grinding
Oil resistance (resistance to Inks)
Excellent abrasion resistance
Hardness range 15-95 (Shore A)

Can be Extruded and Calendared with ease. Excellent grinding finish with compression set property special series are also available for different applications or we can supply as per required specifications.

Rubber Compound Nitrile(Straight)

Hardness Range: 10 to 98 (Shore A)
Temp Resistance: 100°C to 120°C (with special compounding)
One of the best in class of polymers as far as oil resistance is required at economical price. Low compression set properties so one can get better sealing properties, Nip properties, better abrasion properties & can be formulated for longer life or as required.
Ozone resistance can be increased with different combinations to suit customer’s demand.

Rubber Compound Hyplon

Compounds made from Hyplon Rubber have wide spectrum of characteristics including

Resistance to oxygen and ozone.
Excellent abrasion resistance.
Temp resistance range 150^°C
Broad range of acid and alkali resistance including chemicals
Excellent tensile and tear strength

Hardness available 30-95 (Shore A) due to its inert backbone, it is resistant to

Hot aqueous alkalis
Acids
Water
Heat and Chemicals
Flame

Rubber Compound EPDM

Compounds made from EPDM rubber have excellent resistance to ozone chemicals (like acid, caustics, steam water etc) due to its versatile structure and saturated backbone.

Resistance to solvents (like Esters and Ketones)
Temp range 180^°C
Hardness range 20-95 (Shore A)

Can be easily Extruded, Calendared thereby easy to fabricate even in harder compounds.
Application: – Printing, Industrial rollers and Automotives.

Rubber Compound Natural Rubber

Hardness Range: 25 to 100 (shore A)
Temp Resistance: 50^°C to 100^°C.
One of the highly consumed polymers in the world. Mainly it is isoprene. Best properties can be fabricated as far as abrasion, resilience fatigue, Modulus, Tensile strength impact resistance and tear strength are required. Flexing properties can be enhanced with suitable fabrication. Industries like Paper, Textile, Steel, Cement and many more require products made out of it. Aromatic oil resistance is less can be easily extruded, calendared and fabricated due to very good tack.

Rubber Compound Silicon Rubber

Hardness Range: 40 to 90 (shore A)
Temp Resistance: 250^°C
Post Curing/Non Post curing: Both available
Mainly used where continuous high temperature is service is required. Industries where low co-efficient of friction along with release properties are required. Can be formulated as per required specifications. Can be easily extruded and calendared so easier for making products on Strip Building Machine.

Rubber Compound Neoprene

Because of its inherent oxygen and ozone resistance and crystallization, it offers best mechanical and fair oil resistance.
Hardness Range : 10 to 95 (Shore A)
Temp Resistance : 40^°C to 150^°C (with special compounding)
Due to mechanical, oil resistance, dent resistance, abrasion resistance ease of extrusion and calendaring makes it versatile for various end uses.

A Compound is mixture of various ingredients with its base polymer to obtain the required physical and chemical properties according to industry specifications.

Zenith develops consistent, high standard rubber compounds to meet stringent requirement for roller manufactures for all industries. Zenith also delivers custom mixed compounds. Zenith only uses top quality raw materials. Our vendors/suppliers are required to furnish us with the material certification on every rubber ingredient. Zenith’s custom and advanced mixing facilities include kneader mixing, open mill mixing, straining and calendering that enable Zenith to offer the highest quality standards in its compounds.

Zenith’s technical facilities include state-of-the-art testing equipment and machines that are regularly maintained and calibrated. This enables Zenith to perform different tests and inspections right from raw materials to final product. These tests are for hardness, tensile strength, tear strength, abrasion resistance, fluid resistance, ozone/UV resistance, resilience and ageing among others.

All tests are carried out according to internationally accepted standards and/or the customer’s requirements by qualified and experienced personnel.

After extensive research, Zenith has developed various compounds for hardness ranging from 12 Shore A to 100 Shore A using a wide range of materials such as: NR, SBR, EPDM, NBR, PVC-NBR, CR, CSM, SILICONE (Q) and PU.

Zenith qualified and experienced staff can develop formulations and colour matching for specific requirements. Our extensive formulae library is constantly enhanced to keep pace with the rapid technological development.
