Mule-Hide’s TPO-c EXTRA Membrane is a polyester reinforced, .080” thick, polyolefin based, thermoplastic, heat-weldable membrane. High breaking strength, tearing strength, and puncture resistance is achieved by encapsulating a strong polyester fabric between the top and bottom plies. The .080″ thickness affords higher strength and weatherability when compared to our .045″ and .060″ products. The membrane is environmentally friendly and safe to install. All Mule-Hide TPO membranes include OctaGuard XT™, an industry leading, state of the art weather package that enables Mule-Hide TPO membranes to withstand the extreme weatherability testing which simulates exposure to severe climates.


The TPO-c membrane is used in mechanically attached and fully adhered roofing systems in new construction, reroofing and recover (retrofit) applications. It may also be used as flexible membrane flashings for walls, curbs, etc, when installing TPO-c membrane roofing systems. The system must be installed over an acceptable roof insulation or other suitable substrate. See the Mule-Hide TPO Specifications Manual for complete specifications and details.

INSTALLATION INSTRUCTIONS 1) Approved insulation shall be attached to the roof deck with an approved insulation adhesive or approved fasteners and plates. Install insulation with its largest dimension perpendicular to the direction of the membrane seams where possible. 2) Mechanically Attached Roofing System a) Perimeter sheets to be installed in an approved pattern along all exterior roof edges. b) Mechanical fasteners and plates are installed in the seams of both the perimeter sheets and field sheets and into the roof deck. Use approved fasteners and maintain proper penetration for specific roof deck. 3) Fully Adhered Roofing System a) Perimeter sheets are not required. b) The membrane is required to be mechanically attached at the base of all vertical surfaces, roof edges, and angle changes. c) The field of the roof is fully adhered to the substrate with Mule-Hide TPO Bonding Adhesive. 4) All seams are hot air welded and checked by probing. 5) All details will be done in accordance with Mule-Hide details. 6) On projects where a Mule-Hide Standard or Premium Warranty is requested, an authorized Mule-Hide representative shall inspect all completed work. This is only a brief summary and not the complete specification. The Mule-Hide Specifications, Details, Technical Bulletins, and associated documents should be thoroughly reviewed prior to starting any project. Contact Mule-Hide Products for additional information.


PRECAUTIONS • Surfaces may be slippery when wet, or due to frost and ice build-up. Exercise caution to prevent falls. • Mule-Hide TPO membranes are highly reflective to sunlight. Workers should dress appropriately, wear sunscreen, and wear sunglasses that filter out UV light. • Exercise care when working near roof edge as edges may not be visible when surrounding area is covered with snow. • Store Mule-Hide membrane in original wrappings in a cool, shaded area. Cover with light-colored, breathable, waterproof tarpaulins. Mule-Hide membrane that has been exposed to the elements for approximately 7 days or longer must be prepared with Weathered Membrane Cleaner prior to hot air welding. • Maximum sustained temperature not to exceed 160ºF (71ºC) for TPO membrane. • Use proper stacking procedures to ensure roll stability. Avoid creasing the membrane.


PROTECTION & SAFETY Mule-Hide maintains Safety Data Sheets on all of its non-exempt products. Safety Data Sheets contain health and safety information for your development of appropriate product handling procedures to protect your employees and customers. MuleHide’s Safety Data Sheets should be read and understood by all of your supervisory personnel and employees before using Mule-Hide products in your facilities. Revised June-2016 PDS 09-1110 Page 3 of 4 Product Data Sheet MULE-HIDE TPO-c EXTRA MEMBRANE SUPPLEMENTAL APPROVALS, STATEMENTS AND CHARACTERISTICS 1) TPO-c meets and exceeds the requirements of ASTM D68781 Standard Specification for Thermoplastic Polyolefin Based Sheet Roofing 2) Radiative Properties for ENERGY STAR®, Cool Roof Rating Council (CRRC) and LEEDTM 3) Mule-Hide Tan and White TPO membranes are ENERGY STAR® and California Title 24 rated roof products. MuleHide White TPO membranes are Energy Star compliant. An ENERGY STAR qualified low slope roof product must have an initial solar reflectance of at least 0.65 and a 3-year aged solar reflectance of at least 0.50. Cleaning the aged roof surface is not permitted by the ENERGY STAR test protocol. Energy Star is only valid in the United States for Roofing Products. The Cool Roof Rating Council (CRRC) does not specify minimums for reflectance or emittance but they do require specific protocols for testing and reporting. Cleaning of the aged roof surface is not permitted for determination of radiative properties after 3 years. A LEED “point” may be earned if a roof material is ENERGY STAR qualified and has a thermal emittance of at least 0.90 as determined by ASTM E408. Solar Reflectance Index (SRI) is calculated per ASTM E 1980. The SRI is a measure of the roof’s ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. Materials with the highest SRI values are the coolest choices for roofing. Due to the way SRI is defined, particularly hot materials can even take slightly negative values, and particularly cool materials can even exceed 100. California Title 24 requires an initial minimum reflectance of 0.70 and emittance of 0.75 as determined by CRRC. 4) TPO-c membranes conform to requirements of the U.S.E.P.A. Toxic Leachate Test (40 CFR part 136) performed by an independent analytical laboratory. 5) TPO-c was tested for dynamic puncture resistance per ASTM D5635-04 using the most recently modified impact head. 80-mil was watertight after an impact energy of 30 J (22.1 ft-lbf) 1Copyright © ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959, USA EXTREME TESTING FOR SEVERE CLIMATES ASTM Standard D6878 is the material specification for Thermoplastic Polyolefin-Based Sheet Roofing. It covers material property requirements for TPO roof sheeting and includes initial and aged properties after heat and xenon-arc exposure. As stated in the standard, “the tests and property limits used to characterize the sheet are values intended to ensure minimum quality for the intended purpose.” Mule-Hide’s goal is to provide TPO membranes that exceed the requirements of ASTM Standard D6878.

Oxidation (reaction with oxygen) is one of the primary chemical degradation mechanisms of roofing materials.
