OBSH-1 Blowing Agent

The supplied OBSH-1 manual describes a change to OBSH decomposition rate, intended to evaluate cure matching in selected rubber systems.

OBSH-1 is distinct from OBSH. An adjusted release rate is not proof of improved performance on every EPDM compound.

Evaluate OBSH-1 for selected rubber cure systems, including the EPDM seal application identified in its manual.

Provide the exact compound, cure system, actual material temperature, residence time and target cells. A material name alone is not sufficient to establish suitability. Finished-part performance must be verified on the customer’s formulation and equipment.

Reference values below belong only to OBSH-1. They are not a current batch certificate; methods, revision and acceptance limits need confirmation.

Pending confirmation Current TDS/SDS/COA, test methods and batch acceptance criteria remain pending; do not transfer these values to another model.

OBSH-1 is distinct from OBSH. An adjusted release rate is not proof of improved performance on every EPDM compound.

Record the formulation, cure/crosslinking system, dispersion, actual material temperature, pressure, residence time and cooling. No universal dose, reduction in odour, weight saving or mechanical-property guarantee is assigned to this grade.

1. Current baseline: keep the existing compound, blowing agent, dosage and process; record the current result.
2. Direct replacement: change only the candidate blowing agent to distinguish the grade effect.
3. Optimised condition: review temperature, time, line speed, pressure or cooling within the customer’s permitted range.
4. Alternative route: compare a second grade or a compound route where the evidence supports it.

Record density, cell distribution, shrinkage, colour, mechanical properties, odour and process stability. The customer’s finished-part specification determines acceptance.

TDS

Specification, method and revision for the selected model.

SDS

Handling, storage and transport information for the actual product.

COA

Results for the supplied batch, separate from general brochure values.

Pending confirmation Current model-specific TDS/SDS/COA and applicable original reports are not attached to this preview. No certificate or download button is fabricated.

The supplied manual lists a 25 kg pack with an inner plastic liner, in a carton or kraft paper bag. Confirm the order’s pack format and destination requirements separately.

Its storage note calls for a cool, dry place away from sparks, fire and heat. Use the current grade-specific SDS for safety instructions, emergency measures and transport classification. The manual is not a replacement for that document.

Pending confirmation Shelf life, MOQ, dispatch time, pallet/loading plan and current transport classification require order-specific confirmation.

OBSH, OBSH-1, TSH, H and low-temperature H remain separate models. Similar packaging or a shared application does not establish interchangeability.

Share the actual material and process, current issue, target properties, quantity and destination.
