Why this hose?

CP SIL 460 is the silicone variant in the CP clamp profile family. Silicone offers a specific combination of properties: high temperature tolerance (+280 °C peak), good flexibility at cold temperatures, and flame retardancy per DIN 4102-B1.

INOX clamp profile ensures corrosion resistance in hot processes where condensation can corrode standard galvanised steel. The hose is the preferred choice when both temperature tolerance and flame retardancy are needed, but not ATEX approval.

Where it is used

In practice CP SIL 460 is seen at glass industry extraction, ceramic process extraction and metal smelting extraction.

The formal product name is CP SIL 460. In daily use: "silicone-CP" or "460".

Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.

Standards and compliance

The hose is certified or documented to the following standards:

  • DIN 4102-B1. German building material classification.
  • REACH (EC 1907/2006) and RoHS 2011/65/EU. The manufacturer holds declarations of compliance.

Industries that use it

The hose is used in high-temperature industries:

Glass, ceramic and metal industries use the hose for extraction at smelting and hot processes.

Custom lengths and assemblies

The hose can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies.

We offer guidance on material choice, coupling system and grounding, so the hose fits correctly into the overall system. If there is any doubt about zone classification or resistance requirements, a short conversation before ordering is well worth the time.

Frequently asked questions

What is the difference between silicone (CP SIL 460) and aramid (CP ARAMID 461)?

Both are high-temperature clamp profile hoses. Silicone (460) has up to +280 °C peak; aramid (461) has +300 °C peak. Aramid has better flame retardancy (M1 class) but silicone has better flexibility at cold temperatures. For hot processes, the difference is primarily in the strictness of flame retardancy — aramid where fire resistance is critical, silicone where temperature cycles are central.

Can the hose be supplied cut to length with couplings?

Yes. CP SIL 460 can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies. We provide guidance on coupling system and sealing so the hose fits correctly into the overall installation.

How do I order the hose, and where do you deliver?

The hose is ordered through Particulair (Karlslunde, Denmark). We deliver to Denmark, the EU and selected third countries such as Norway and Switzerland. Standard dimensions can typically be delivered in 1-2 weeks; custom assemblies and larger volumes require slightly longer lead time.

What is the hose's expected service life?

Service life depends on operating conditions: loading, temperature, chemical exposure, UV and mechanical movement. In standard industrial use, expected life is 3-7 years. Aggressive conditions (high temperatures, continuous flexing, chemical vapours) reduce service life. We recommend regular visual inspection for cracks, deformation or discolouration.

How is the hose best stored before use?

Store the hose dry, at room temperature (15-25 °C) and out of direct sunlight. Avoid contact with ozone-generating equipment (welding equipment, engines). If stored on a reel, the bend must be larger than the specified minimum radius to avoid permanent deformation. Proper storage significantly extends shelf life.

What is the minimum bend radius, and what happens if I go below it?

Minimum bend radius is the smallest radius the hose can be bent to without permanent deformation or internal damage. The table above shows specific values for each dimension. Bending the hose below this limit can collapse the wall, kink the spiral or damage the inner coating. The result is reduced flow, increased pressure loss and shorter service life. Always use bend radius as a design constraint in installation.

Which chemicals is the hose resistant to?

Specific chemical resistance depends on material selection, concentration and temperature. The manufacturer maintains an extensive chemical resistance table showing compatibility for hundreds of chemicals. It can be downloaded from the Documentation section above. If in doubt about a specific chemical or mixture, contact Particulair — we can advise based on your concrete process.

Does temperature affect the hose's chemical resistance?

Yes, significantly. Higher temperatures accelerate chemical attack and reduce the material's resistance. A hose fully compatible with a chemical at 20 °C may be underrated at 60 °C. The manufacturer's chemical resistance table typically lists values at 20 °C; at higher operating temperatures, compatibility must be reassessed. We always recommend a consultation before choosing a hose for chemical transport at elevated temperatures.
