P36 Saddle Washer

P36 Saddle Washers Aztec Washer P 36 saddle washers

Improved

Shape memory - same sealing properties even after repeated installation, high expansion or contraction factor - permanent seal, improved resistance to weather degradation - prolonged life span, excellent heat resistance - allows powder painting in standard or special colors.

Facing Materials

Our new "Polymer 36" is a result of industry demand and available technology. The unsuitable memory and wear characteristics of sponge and foam have been eliminated.

The unsuitability of powder painting the part after the sponge has been glued on has been eliminated. Polymer 36 has been developed to withstand the temperatures required to fully cure powder paint and still retain a full and complete bond between the polymer and its aluminum substrate. Memory characteristics very similar to solid polymers have been achieved thru experimentation in chemical technologies and our own expertise in vulcanizing.

Backing Materials

Our selection of backing material involves three
primary considerations: strength, corrosion
resistance and cost.

Aluminum

Aztec’s special alloys provide good performance when moderate strength and deflection requirements exist. For higher stress applications, improved strength and corrosion resistance may be attained by a selection of specialty alloys and tempers such as 5052-H38. Use of an aluminum P36 saddle washer also minimizes concerns of galvanic corrosion in certain installations.

Saddle Washers Are More Than Just A Washer

Because of a unique bonding process, which bonds a strong backing material to a resilient facing material, Aztec’s P36 saddle washers will perform a function that neither material could perform alone. Where sealing challenges are presented, the conical design directs the flow of the elastomeric portion toward problem areas. When problems call for cushioning or vibration control, the facing material will also provide the solution.

Features Include:

  • Quality elastomerics, meeting the need for elasticity, memory, temperature extremes, chemical, ozone and sunlight-resistance.
  • Conical design directs flow of facing materials to form a seal conforming to both fastener and sealing surface.
  • Full-face design cushions fragile surfaces and minimizes vibration.
  • Choice of various colors and finishes

Cushioning and Vibration Control

40 Years of proven experience in testing and retesting compounded formulas have led to the perfection of Aztec’s P36 saddle washers. Our washers possess extraordinary elasticity and memory when cushioning and vibration control are needed. As the saddle washer is compressed and fastened against a substrate, the facing material serves as a permanent cushion.

P36 saddle washers solve a variety of problems in numerous applications including:

  • Noise Control
  • High Winds

Aztec’s unique P36 saddle washer products are designed to provide a permanent seal in a wide variety of applications, including:

  • Metal roofs and siding where the expansion and contraction of metal require a permanent resilient seal

A P36 saddle washer is used for fastening of roof coverings in conjunction with either screws or bolts. It is used as a crown fixing and is therefore placed on top of the corrugations or ribs. The P36 saddle washer has the shape that fits the profile of the roof covering. The P36 saddle washers consist of backing material which usually is steel or aluminum, and facing material which has to be very elastic and has good sealing capabilities.

Standard saddle washer: The saddle washers on the market today are mostly made from the pre-painted steel or aluminium. The facing material is made of a low tensile strength polymer sponge. The current sponge material has poor memory characteristics which does not allow for the expansion and contraction of the panels used in metal building constructions.

P36 saddle washers produced by Aztec are made of an aluminum sheet with a thickness of 1.0 mm or more. Facing material is a nitrogen expanded low durometer EPDM elastomer called "Polymer 36”.

Backing material – Aluminium and facing material – "Polymer 36” are bonded together prior to forming of saddle washer. "Polymer 36”, in addition to its other excellent properties, it has a good temperature resistance.

This allows the powder coating of saddle washer in any RAL, NCS or other special colors. Technology of P36 saddle washers powder coating as well as the machines used are specially developed by Aztec.
