Why Platinum Cured Silicone Rubber Has Become the New Industrial Standard

Why Are Modern Factories Switching to Platinum Cured Silicone Rubber Sheets?
Silicone rubber sheets have been widely used for decades in food, pharmaceutical, medical, electronics, and semiconductor industries.

However, over the past 3–5 years, there has been a very clear shift:
more and more modern factories are switching from conventional Peroxide Cured silicone to Platinum Cured Silicone for critical applications.

This shift is not just a trend.
It is driven by the fact that today’s factories face much stricter requirements on:

• Cleanliness
• Purity
• Safety
• Quality control (QC) and audits

What Is Platinum Cured Silicone – And Why Is It Better?
Platinum Cured Silicone is produced through a vulcanization process using a platinum catalyst.
This curing system delivers performance that is clearly superior to Peroxide Cured Silicone in terms of:

• cleanliness
• durability
• safety

• Higher purity – no by-products, no residual curing agent
• 100% odorless – ideal for cleanrooms and highly controlled production lines
• Better high-temperature resistance – less yellowing, less embrittlement
• Lower compression set – less permanent deformation, longer sealing life
• Easier to qualify for food and pharma applications
• Ultra-smooth, white-transparent appearance – minimizes the risk of contamination build-up
  

7 Reasons Why Modern Factories Are Switching to Platinum Cured Silicone

1) True High Purity – No Peroxide Residuals
Regulations and standards in food, beverage, pharmaceutical, and medical industries are getting stricter every year.
Even a small amount of residual chemicals can cause:

• QC rejection
• Failure in customer audits
• Risk to brand image

• White-transparent appearance makes contamination easy to detect
• Ultra-smooth surface reduces particle build-up

• Cleanroom Class 100–10,000
• Pharma production
• Bio-Tech and Lab environments

3) 100% Odorless – Fewer QC Failures
Peroxide cured silicone often has a noticeable, sometimes strong odor.
In many applications, this odor can:

• Transfer to the product
• Cause sensory failures (taste/smell)
• Trigger customer complaints

Platinum Cured Silicone is truly odorless.
Many factories have switched specifically because it:

• Reduces issues in drinking water gaskets, food contact seals, etc.
• Cuts down product rejection caused by odor contamination

• Steam sterilization
• Autoclave cycles
• Continuous high temperature
• High-temperature oven processes

Even after multiple sterilization or heating cycles:

• Physical properties change very little
• The material remains elastic and functional

5) Lower Compression Set - Longer Service Life
Platinum Cured Silicone generally has a lower compression set than Peroxide Cured types.
This is critical for applications where constant sealing force is required, such as:

• O-Ring Sheet
• Gasket Sheet
• Vacuum Seal
• Pharma Seal

Benefits include:

• Less permanent deformation
• Longer sealing life
• Lower maintenance and replacement costs per year

• Many chemicals
• Cleaning agents
• Mild-to-moderate solvents
  

It is:

• Easy to clean
• Less likely to absorb liquid

This makes it suitable for systems that require frequent sanitization and cleaning.

7) The New Global OEM Standard
Many international OEMs now specify Platinum Cured Silicone in their technical requirements and drawings.
Why?

• To comply with stricter global standards
• To secure long-term safety and cleanliness
• To support regulatory approvals in multiple countries

HyperSheet^® – The Only Brand in Thailand Producing Industrial-Grade Platinum Cured Silicone Rubber Sheets
This is where HyperSheet^® stands out in the Thai market.
HyperSheet^® is the only brand in Thailand that develops and supplies true Platinum Cured Silicone Rubber Sheets specifically for industrial applications.

5 Reasons Why Factories Trust HyperSheet^® Platinum Cured Silicone

1) High Tensile Strength > 7 MPa - Clearly Stronger Than Standard Grades
Typical Platinum Cured silicone sheets in the market: 4–6 MPa
HyperSheet® Platinum Cured: ≥ 7 MPa
This means:

• Higher tear resistance
• Better mechanical durability
• More reliable performance under load and movement

2) Ultra-Smooth Transparent Surface

• Uniform, smooth, white-transparent surface
• Low surface roughness

Perfect for:

• Cleanroom environments
• Pharma production
• Beverage and liquid processing
• Semiconductor and high-tech electronics

3) Ultra-Pure Grade – Among the Cleanest Available in Thailand
HyperSheet^® Platinum Cured Silicone is engineered to deliver:

• No harmful residuals
• No peroxide residue
• No odor

4) Compliant with Food & Pharma Requirements
HyperSheet^® Platinum Cured Silicone can be used in applications that require:

• Compliance with FDA 21 CFR 177.2600
• Direct or indirect product contact
• Use in medical-related devices, beverage lines, and pharma production lines

• Thickness: 0.5–25 mm
• Width: 1.2 m
• Standard length: 10 m per roll
• Color: transparent (clear)
• Options: Cut-to-size sheets | PSA backing (adhesive tape) | Die-cut gaskets | Sheet / Roll / Custom sizes
  

Who Should Switch to Platinum Cured Silicone Now?

• Food & beverage factories
• Pharmaceutical and biopharma plants
• Medical device manufacturers
• Cleanroom / electronics / semiconductor industries
• Systems using steam or autoclave
• Factories with strict QC on odor and residuals
• Manufacturers tired of dealing with seal deformation and compression set issues
  
  

Why Choose HyperSheet^® Over Generic Silicone Sheets?
Because HyperSheet^® is the only brand in Thailand that combines these three critical pillars:

• 100% Platinum Cured technology
• Tensile strength > 7 MPa – premium mechanical performance
• Full B2B / OEM support – with complete documentation (COA, FDA, QC Report)
  

By choosing HyperSheet^®, you are upgrading your factory standard to match global requirements and making audits easier year after year.
