Important Compatibility Note

While EPDM is exceptional for heat and steam applications, it is critically important to note that EPDM should NOT be used in contact with:

• Petroleum-based oils and fuels

• Aromatic hydrocarbons (benzene, toluene, xylene)

• Aliphatic hydrocarbons (gasoline, kerosene)

• Chlorinated solvents

Contact with these fluids will cause significant swelling, loss of mechanical properties, and premature failure . For applications involving oil contact, we recommend consulting our technical team for alternative materials such as NBR or FKM.

PART 3: PRODUCT LINE - COMPREHENSIVE TECHNICAL SPECIFICATIONS

L-Shaped Door Packing: Engineering the Perfect Seal

Design Philosophy: The Self-Energizing Principle

The L-shaped geometry of our steriliser door packing is not arbitrary—it is a carefully engineered solution based on fundamental pressure vessel sealing principles. The "L" configuration creates a self-energizing seal that leverages the internal pressure of the sterilizer to enhance sealing force.

How Self-Energizing Works:

1 Initial Compression: When the door closes, the L-shaped leg compresses against the door frame, creating an initial seal at low pressure.

2 Pressure Activation: As steam enters the sterilizer and pressure builds, the medium exerts force on the internal surfaces of the L-shaped geometry.

3 Enhanced Sealing: This internal pressure pushes the seal more firmly against both the door groove and the frame, with sealing force increasing proportionally to internal pressure.

4 The Result: At 3.0 bar operating pressure, the sealing force is significantly higher than the initial mechanical compression, ensuring zero leakage even with minor door misalignment.

Why EPDM is the Optimal Choice for Sterilizer Doors

1 Steam Resistance: EPDM's saturated polymer backbone provides exceptional resistance to steam hydrolysis, maintaining physical properties even after thousands of sterilization cycles .

2 Temperature Performance: With continuous operation up to 150°C and peaks to 160°C, our EPDM formulation comfortably handles standard palm oil sterilization temperatures of 135-145°C .

3 Compression Set Resistance: The peroxide-cured system ensures the seal returns to its original shape after door opening, maintaining sealing effectiveness over thousands of cycles.

4 Weathering Resistance: For outdoor installations exposed to Borneo's intense tropical sun and humidity, EPDM's excellent UV and ozone resistance ensures no surface cracking or degradation .

5 Cost-Effectiveness: Offering the best balance of performance and economy for standard palm oil applications.

PART 5: ENGINEERING INSTALLATION GUIDE

Proper Installation Procedures for Maximum Service Life

Pre-Installation Preparation

Safety First:

• Verify sterilizer is completely depressurized (0 bar)

• Confirm temperature has cooled below 50°C

• Lock out/tag out all energy sources

• Use proper personal protective equipment (PPE)

Groove Inspection:

1 Clean the seal groove thoroughly using non-metallic scrapers to avoid damaging the groove surface

2 Remove all old seal residue, rust, scale, and debris

3 Inspect groove for:

◦ Corrosion pitting (depth >1mm requires repair)

◦ Deformation or warping (check with straightedge)

◦ Sharp edges or burrs (file smooth)

4 Measure groove dimensions to confirm correct seal size selection

Installation Steps for L-Shaped Packing

Method A: Installation in Bulk Roll Stock

1 Pre-Stretch Calculation: EPDM should be installed with 2-3% stretch for optimal groove retention. For a 2,300mm diameter door, cut length = π × diameter × 0.97 = approximately 7,000mm.

2 Starting Point: Begin at the bottom of the door (6 o'clock position) to allow gravity to assist.

3 Seat the L-Leg: Ensure the L-shaped leg fully engages the groove corner. Use a rubber mallet gently to seat the seal completely.

4 Even Tension: Work simultaneously on both sides from bottom to top, maintaining even tension to prevent twisting.

5 Corner Management: At door corners (if applicable), avoid sharp bending—maintain consistent radius.

6 Final Cut: When ends meet at top, mark, remove, and cut with a sharp, water-lubricated knife at a 45° angle for scarf joint.

Method B: Installation of Joint Endless Rings

1 Verify Size: Confirm ring diameter matches door groove diameter.

2 Lubrication: Apply a thin film of food-grade silicone lubricant to the groove and seal.

3 Positioning: Place ring at bottom of door and work upward on both sides simultaneously.

4 Final Seating: Use a smooth, round tool to ensure full groove contact around entire circumference.

5 Compression Check: Close door partially and check for uniform contact pattern.

Field Splicing Techniques

When using bulk roll stock, proper splicing is critical:

Scarf Joint Method (Recommended):

1 Cut both ends at matching 45° angles

2 Clean surfaces with isopropyl alcohol

3 Apply EPDM-specific adhesive or vulcanizing solution

4 Join ends with light pressure

5 Allow proper cure time before door operation

Hot Vulcanizing (Permanent):

1 Prepare scarf cuts as above

2 Apply uncured EPDM splicing compound

3 Use portable vulcanizer at 150°C for specified time

4 Resulting joint strength equals parent material

Service Life Optimization

To maximize the 18-24 month service life of your RUBASIA EPDM steriliser door packing:

1 Maintain Proper Door Alignment: Misaligned doors cause uneven compression and premature failure.

2 Control Operating Parameters: Stay within 3.0-3.5 bar and 135-145°C for optimal life.

3 Avoid Oil Contamination: Prevent lubricating oils or hydraulic fluids from contacting the seal.

4 Clean Groove at Each Change: Always start with a perfectly clean groove surface.

5 Proper Storage of Spares: Store EPDM in cool, dark, dry conditions away from ozone sources (motors, welders).
