Customer Feedback
We evaluated this polyimide silicone tape in our internal testing, and it was a suitable option for our application requirements. The product quality was consistent, and the technical guidance provided by your team was helpful during evaluation and use.

We have worked with your team for more than ten years on PET Fiberglass Cloth Tape. From order handling to packaging and shipment coordination, communication has been smooth and support has been consistent throughout the cooperation.

At the beginning, we wanted to confirm that this filament reinforced electrical tape would be suitable for our operating conditions in South America. After evaluation, it proved to be a reliable option for our high-voltage transformer manufacturing requirements.

Frequently Asked Questions About River Tape
River Tape supplies industrial customers, OEMs, and distributors in international markets. Shipment methods, Incoterms, export port, and freight arrangements depend on the destination, order volume, and quotation. Applicable commercial and shipping documents are confirmed before ordering. Please provide the destination country and preferred shipping terms when requesting a quotation.
Please provide the intended application, substrate, required tape function, continuous and peak temperature, exposure time, thickness, width, roll length, core size, winding direction, estimated quantity, packaging requirements, and any required technical or compliance documents. If you are replacing an existing tape, a current sample, TDS, photograph, drawing, or failure description can help us make a more accurate comparison.
TDS is available for applicable product grades. SDS or product safety information can be provided where applicable. REACH, RoHS, SVHC, CoC, inspection reports, or other documents may be available according to the exact product, destination market, qualified order, and agreed documentation scope. Please identify all required documents before sample approval or ordering.
MOQ and lead time depend on the selected tape construction, dimensions, roll format, packaging, material availability, and order quantity. Standard grades and sample requirements are generally easier to arrange than custom constructions, die-cut parts, or private-label programs. The applicable MOQ and production schedule are confirmed after specification review.
Yes. Samples are available for application evaluation and product qualification. Selected grades can also be supplied in custom widths, roll lengths, core sizes, winding directions, finished rolls, log rolls, sheets, die-cut parts, and selected larger roll formats. Availability, tolerances, sample format, and converting feasibility depend on the tape construction, adhesive, reinforcement, liner, requested dimensions, and order quantity.
Inspection is performed according to the selected product and agreed order specification. Applicable checks may include material and grade identification, dimensions, roll condition, winding, appearance, labeling, packaging, and batch identification. Technical properties are reviewed where they form part of the applicable inspection plan or customer agreement. Product, batch, and order records support comparison between repeat deliveries.

No. A temperature rating alone does not establish application suitability. Selection should also consider whether the exposure is continuous or short-cycle, peak temperature, dwell time, number of cycles, substrate, process chemicals, electrical requirements, mechanical load, residue sensitivity, and removal conditions. A tape used for a short powder-coating bake is not automatically suitable for continuous service on heated equipment or as part of an electrical insulation system. Please confirm the operating profile and test a sample under the actual process conditions.
The suitable tape family depends on what the tape must do. Polyimide tapes are commonly evaluated for electronics masking, higher-temperature processing, and electrical insulation. PET silicone tapes are often selected for powder coating and shorter high-temperature masking cycles. PTFE tapes are used for heat sealing, non-stick surfaces, and low-friction processing. Glass-cloth and reinforced electrical tapes support motor, transformer, coil, and lead-wire applications. Filament strapping tapes are intended for bundling, carton reinforcement, palletizing, and transport securing. The exact grade should be confirmed against the application conditions.
