Butyl Rubber Extruder Machine

The Butyl Rubber Extruder Machine is used to produce butyl rubber tapes, water-swelling strips and related products for sealing, waterproofing, damping, sound insulation and automotive seals. It can also produce specialty tapes (aluminum-foil, release-paper, non-woven) and certain industrial bases such as chewing gum base material.

A typical butyl tape production line includes a cold-feed vacuum extruder, a high-temperature forming (vulcanization) unit (3 m length in the supplied line), a winding machine, and PLC-based control systems for process automation.

Models include XJ-45, XJ-65, XJ-80 and XJ-110. Screw diameters are 45, 65, 80 and 110 mm respectively, with L/D ratio 12:1. Typical outputs are: XJ-45 (20–30 kg/h), XJ-65 (40–60 kg/h), XJ-80 (120–150 kg/h) and XJ-110 (200–280 kg/h).

Motor power varies by model (approximately 7.5 kW for XJ-45, 11 kW for XJ-65, 15 kW for XJ-80 and 30 kW for XJ-110). Screw speed range is 10–70 (adjustable) to control throughput and product quality.

Yes. The extruder line is designed to produce water-swellable butyl rubber strips used for joint sealing and waterproofing in tunnels, highways and other infrastructure where swelling upon exposure to water improves sealing performance.

Yes. The extruder can be customized to accommodate different tape widths, thicknesses, backing materials (foil, release paper, non-woven), formulation changes and winding requirements to meet specific production needs.

Typical inputs are butyl rubber compounds blended with fillers, tackifiers, plasticizers, and any additives needed for water-swellable behavior. For laminated products, backing materials such as aluminum foil, non-woven substrates or release liner are also required.

After extrusion, the extrudate passes through a high-temperature forming and vulcanization section (the 3 m heated forming machine) to shape, crosslink and set the tape before cooling and winding. Temperature and dwell time are controlled via the PLC.

Standard features include PLC process control for temperature, screw speed and line speed, emergency stop buttons, safety guards, interlocks, and sensors for temperature and pressure monitoring. Additional safety options can be added upon request.

Choose based on required hourly throughput, tape width/thickness, and downstream processing. For pilot or low-volume production select XJ-45/XJ-65; for medium to high volume choose XJ-80 or XJ-110. Consult technical sales with target capacity and product specs for a recommendation.

Regular maintenance includes cleaning the extruder barrel and screw, inspecting and replacing worn screw and barrel components, checking heater bands and thermocouples, lubricating bearings and gearboxes, and verifying vacuum and winding systems. Follow the supplier's maintenance schedule for intervals.

Common quality checks include dimensional tolerance (width/thickness), adhesion/tack tests, tensile and elongation, water-swelling performance (for swellable strips), vulcanization/crosslink density checks and visual inspection for surface defects.

Requirements include a stable foundation, appropriate electrical supply matching motor ratings, adequate ventilation and exhaust for heating zones, compressed air or vacuum systems if specified, and sufficient floor space for the extruder, vulcanization line and winding unit. Exact requirements are provided with purchase documentation.

Manufacturers typically provide operator training, commissioning assistance, spare parts packages and technical support. Ask your supplier about available training (on-site or remote), recommended spare parts, service contracts and typical lead times for parts.

Lead time depends on configuration and order volume; typical manufacturing lead times are several weeks to a few months. Warranty and service terms vary by supplier—confirm standard warranty duration, coverage and available extended service agreements with your sales representative.
