Peristaltic pump tubing is used in specialized applications of pharmaceutical, biotechnology and laboratory. Some of the types of tubingareSilicone tubing, Viton tubing, Thermoplastic elastomer tubing( TPE/ TPV tubing). In these applications, the fluid will only be in contact with tubing thereby avoiding any contamination. This peristaltic pump tubing is highly durable, resistant to fatigue, ozone, ultraviolet, acids, alkalies, water, and most oils and lubricants. Therefore becoming one of the best suited tubings for critical applications of biopharma industry.

Transparentsilicone tubing offers the transparency and having one of the least extractables. Viton tubing offers excellent chemical resistance to the majority of the chemicals due to fluorine atoms in the chemical chain. This allows it to be used with most of the corrosive liquids where other tubings would fail. Westoprene tubing is used for special applications where long life and resistance to certain types of chemicals is required.

Silicone braided hose is thick tubing in which a polyester or Nylon multifilament yarn braiding is sandwiched between two silicone layers to give reinforcements. These hoses can withstand high pressure due to reinforcements. Due to the rigidity of the structure, certain silicone steel coiled hoses are extremelyefficient in preventing wall collapse during vacuum pressure. Western Rubbers India Pvt Ltd. has the expertise and in-house facility to manufacture these hoses

These food grade silicone hoses are extensively used in Pharmaceutical, healthcare, cosmetics, and life science fields because of their transparency, chemical inertness, and rigidity.

Chemically extremely stable and suitable for use with many acids, alkalis and other pharmaceuticalcleaning agents. Hence one of the best material for transfer of fluid under high pressure.

• 100% food grade ( FDA Compliant USP-21CFR177.2600 and USP Class Vl complaint)
• USP-28 Toxicology tested
• UV, ozone and Corona resistant
• Burst pressure test certified hoses.
• Autoclavable.
• Standard sizes available ex-stock

• Silicone hose with single nylon braided
• Silicone double braided nylon hose

• Steel coiled silicone hose

(Note: Stainless steel Clamp fitted in custom lengths on request)

• Transfer and monitoring of high pressurized fluids inpharmaceutical industry
• Used inDairy industrybecause of chemical stability
• Health care and cosmetics industryuse silicone braided hoses to transfer raw materials
• Used for transfer of bacterial growth feeds and Ph balancing fluids inlife sciences and virology labs.

Western Rubbers made silicone braided hose with ss crimping end are a blend of flexibility and strength. Their Ultra flexibility, fiber reinforcement, and FDA compliance make them one of the most suitable media for fluid transfer. These hoses are made up of nylon reinforcements whichenhancesits physical property to withstand compressiveas well as bulk expansion forces. The end clamps are custom fit as per users required lengths. The crimped end clamps are made in SS 316L for FDA compliances.

Transparent Silicone tubing is used in various industries likepharmaceutical, medical, cosmetics, food processing, chemical plants and other allied industries. Even though the cost of silicone elastomer is higher than other polymers, but itspreferred choice by engineers, designers and users especially in high-end applications. The unique property of chemical resistance or chemical inertness is due toSiloxane molecule. With this property silicone has another exclusive property that it is can be manufactured to give crystal clear transparency makes it ideal for usage in fluid handling.

Peroxide based cure system

Advantages:

• Peroxide based cure systems were traditional types of cure systems.
• Peroxide based silicone curing is cheaper
• Imparts better physical properties than platinum based silicone

Disadvantages:

• Product post curing is necesary to remove unreacted peroxide traces from the surface.
• Extractables may have peroxide traces.

Platinum Based Cure system

This is anadvanced curing system.Platinum complex is the cure initiator and accelerator

Advantages:

• Silicone tubing can be manufacturerd with high transparency
• These kind of tubing haveno contaminationdue to substrate.
• Silicone tubing has flame reatardant properties, which makes is excellent for anesthetic applications
• FDA compliantand recommended for food and medical usage.

Disadvantages:

• Comparatively costlierthan peroxide based silicone tubing
• Physical properties are not as good as peroxide based tubing

• Temperature resistance from-30C to 220C
• Chemical resistance to a range of fluids and solvent
• UVresistance
• Coronadischarge resistance
• FDA compliantand Food grade tubing

Note: Leeching and adsorption may happen in certain solvent, kindly contact us before using in critical processes if you are unsure about the chemical resistance properties.

• Pharmaceutical industry for fluid transfer
• Virology, laboratory, fungal growth incubatorsfor transfer of pH neutral, pH acidic or pH basic solvents
• Anesthetic tubingfor transfer of nitrogen-oxygen or helium-oxygen gases
• Food processing industry for transfer ofPulp and low viscosity juices
• Dairy industryfor fluid transfer
• Used insurgicalproduct manufacturing equipements
• Trasnfer of chemically reactive fluid inchemical plants

Fluoroelastomer also commonly known as FKM is a nothing but fluorinated polymer. Due tohigh electronegativity of Fluorine, it is difficult to displace fluorine atoms from the polymeric chains. Therefore FKM elastomer has higher chemical resistance and temperature resistance.Fluorine forms very strong bondwith the polymer chains which makes FKM elastomer very stable andchemically inertto a many inorganic and organic solvents, oils, petroleum products etc. Due tosuperiority to most of the elastomers, Viton tubing is very widely used in harsh environment consisting of corrosive chemicals and higher temperatures.

• Chemically inert to many solvents specially hydrocarbons
• Can be compounded to have temperature resistance up to 300 C
• Has flame retardant properties

Note: FKM elastomer is not recommended for usewithketonessuch asacetone, andorganic acidssuch asacetic acid. For details on compatibility kindly contact us so that our technical representatives can guide you.
