Pressure-sensitive Tapes (PST) Explained

Pressure-sensitive tapes (PSTs) are used across a range of industries, where reliable adhesion and ease of use are essential. These tapes bond with light pressure alone, without the need for heat, solvent, or water. From aerospace cabins to marine hulls and automotive interiors, PSTs provide clean, efficient adhesion for a wide variety of applications.

Let’s take a deeper look at how these tapes can help you deliver professional masking results while saving time.

What are pressure-sensitive tapes (PSTs)?

Pressure-sensitive tapes are adhesive tapes that form a bond when pressure is applied. The bond occurs without needing activation by heat or water. This makes PSTs versatile and fast to apply.

PSTs come in a variety of forms to suit the needs of a range of professionals. Foam tapes offer cushioning and gap-filling capabilities while also offering some sound-dampening. Film tapes are strong and can be translucent to help with accurate application, while foil tapes offer excellent resistance to heat and moisture.

There are several different types of pressure-sensitive adhesives, including the following:

Rubber-based adhesives

Rubber-based adhesives have a strong initial tack and bond well to rough or low-energy surfaces, as well as resistance to oils, fuels, and some chemicals.

Acrylic adhesives

Provide durability and resistance to UV and temperature changes.

Silicone adhesives

Silicone adhesives are best for surfaces that are likely to come into contact with water, like pipes or boats, and in extreme temperatures that might be experienced in a ventilation system.

Key benefits of PSTs

PSTs have many benefits that separate them from other forms of tape. Firstly, they’re quick, clean and easy to apply because there’s no need to activate them with heat or light, saving space in your toolbox and time.

They also offer excellent adhesion to a variety of surfaces. This versatility will give you the confidence to tackle tasks that might usually require multiple rolls of tape.

Sectors that work with PSTs and how they’re used

Pressure-sensitive tapes are essential in sectors that require precise, reliable, and efficient bonding solutions. Here are some key ways these tapes are applied in different industries.

Aerospace

In the aerospace industry, PSTs help to reduce weight and improve structural integrity.

They are used to:

• Bond lightweight interior panels and trim components
• Dampen vibration in aircraft cabins
• Provide thermal and flame barriers for safety
• Assist with assembly
• Mask surfaces during painting and maintenance

Marine

Marine professionals rely on PSTs for sealing, bonding, and protection in harsh environments. PSTs used in marine settings must handle moisture, UV exposure, and temperature shifts while maintaining performance.

These tapes are used to:

• Seal and waterproof electrical components
• Prevent corrosion in saltwater conditions
• Carry out repairs on hulls and deck fittings
• Dampen vibration in engine compartments
• Mask surfaces during painting and maintenance

Automotive

Automotive manufacturers and repairers use PSTs for both structural and aesthetic applications. PSTs help streamline assembly and maintenance processes in vehicle production and repair.

They are used to:

• Mounting exterior trim and interior components
• Damping sound and vibration in door panels and dashboards
• Mask surfaces during painting and maintenance
