rubber sheets

Rubber Sheets Sourcing is an independent sourcing partner for US plant buyers who need rubber sheets as calendered plate for gasket stock, industrial floor liners and wear pads — not gym mats. Share compound, Shore A hardness, thickness, sheet size, quantity and destination so factories can return wholesale quotes on the same line.

What a rubber sheets request has to contain before factories can answer

This desk issues one written list. It does not reprint a factory hardness, tensile strength (MPa or psi) or compression set (%) figure as its own rating.

TDS / SDS library ask

Ask the plant for the current TDS and SDS that name the quoted compound. A company brochure is not that file.

FieldBuyer writes
Shore A hardnessTarget durometer the receiving plant will check
ASTM methodD2000 callout or named hardness / tensile method

Material selector

NBR, EPDM, SBR and neoprene share Shore A language. They do not share oil, ozone or outdoor behaviour. The buyer still names the compound.

Which part of the rubber sheets specification stays the buyer’s decision

Factories can quote after the axes below are written. Missing axes become the supplier’s silent default. Rubber Sheets Sourcing does not fill them.

What separates rubber sheets from neighbouring options

  1. Plate, not foam

    Calendered NBR, EPDM, SBR or neoprene plate is in scope. Foam rubber sheet is a different construction and belongs on its own request.

  2. Gym mats stay out

    Retail flooring tiles and fitness mats are excluded from this family. Industrial liners still need thickness, hardness and a named method.

  3. Vulcanized versus TPE

    Crosslinked rubber still holds compression set above continuous 120°C service where many TPE plates lose sealing force. The buyer names the chemistry.

  4. Quantity against each form

    Standard-size, cut-to-size, colored, UV-stabilized or thicker-gauge. Five labels, not five stocked SKUs.

  5. Destination on the same line

    US state or postal code and the delivery window travel with the pallet count. A cheaper unit on a different Incoterm is a different deal.

Files we ask factories to attach

REACH, RoHS, FDA 21 CFR 177, ISO 9001, IATF 16949 and UL 94 names below are request labels. They are not badges this desk wears. A file counts only when it names the quoted rubber sheets grade and lot.

Open Spec Check

REACH

SVHC statement on the quoted compound if the receiving plant asked for it.

RoHS

Restriction statement for the quoted sheet, not a trading-company letter.

FDA 21 CFR 177

Only when food-contact is on the duty and the grade is named.

ISO 9001

Plant system file if requested; it is not a sheet certificate.

IATF 16949

Ask only when the automotive PPAP package requires a plant file.

UL 94

Flame rating belongs on the quoted thickness, not on a family brochure.

Where rubber sheets usually enter a plant brief

Gasket stock

Die-cut blanks after Shore A, thickness and the ASTM method are written.

Floor liners

Industrial liners, not retail gym mats. Gauge and finish stay on the brief.

Wear pads

Abrasion pads still need compound, hardness and finished size.

OEM kits

Cut lists for assemblies. Substitution is a new request.

Procurement scenario, not a customer testimonial: a materials manager sends Shore A 70, 3 mm thickness, 48 × 96 in black NBR blanks and a named ASTM D2000 callout, then asks two factories to price the same pallet count to the same US destination. The cheaper unit on a different Incoterm is a different deal.

Send the rubber sheets axes you already have

We will issue the same list to more than one factory. Missing fields stay visible. We do not publish a price list or a market-beating percentage.
