OBSH Blowing Agent

The supplied OBSH manual describes a white hydrazide blowing agent with a relatively low decomposition temperature and fine-cell foaming applications. It identifies rubber foaming as a principal use and also mentions selected polyolefin and adhesive applications.

These application directions are a starting point for evaluation. They do not establish compatibility with every rubber, plastic or adhesive formulation. OBSH and OBSH-1 are separate grades; do not substitute the specification of one for the other.

For rubber foaming, provide the polymer and grade, the current formulation, cure or crosslinking system, actual material temperature, residence time and intended cell structure. The service source covers EPDM, NBR, SBR and other rubber systems; individual suitability remains subject to trials.

Compare density, surface condition, cell structure, dimensions and mechanical properties under controlled conditions. For a polyolefin or adhesive enquiry, confirm the intended function and processing conditions before treating the manual’s application note as a recommendation.

The following values are transcribed from the supplied OBSH manual, not a current batch certificate or an approved purchasing specification.

Pending confirmation Current TDS revision, test methods, batch COA, shelf life and purchasing acceptance limits remain to be confirmed. No cross-grade parameter transfer is permitted.

Match gas release to the point at which the compound can retain gas and the cure system can stabilise the cells. Record mixing and dispersion, actual material temperature, pressure, speed, residence time and cooling.

Dosage, activation conditions and cure adjustments are formulation-specific. No universal addition rate, density reduction, mechanical-property guarantee or market-wide compliance claim 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.

Rubber foaming selection and trial planning

Other grades such as OBSH-1, TSH and H require their own model review; each has its own manual and source-specific record. This page does not transfer specifications between models.

Pending confirmation A verified customer case and related test results are not yet available.

Share the rubber grade, cure system, current blowing agent, actual temperature, target density or cells, expected quantity and destination.
