PPT THERMAL GAP PAD
How to order
Thermal Gap Pad - PPT-10
Product Features Typical Applications
Thermal Gap Pad is designed to be used in the applications that require the minimum amount of pressure on components and high thermal conductivity. PPT Thermal Gap Pad is very conformable, filled silicone rubber material and has 1-8W/mK based on hot disk thermal conductivity grades. It is easy to fill in air gaps between PC board and heat sinks or a metal chassis.
Our unique silicone chemistry ensures high compliance to surface irregularity and good surface wetting property, thus offering very low Thermal Contact Resistance at Thermal Joint, and very efficient heat transfer between hot spots and heat sink.
Our Thermal Gap Pad is highly tacky to most surfaces, so no PSA is required. Optionally, we offer one side non tacky to facilitate application that requires the easy removal of hot side component.
Optional Single or 2 Sides Tacky
RoHS Compliant
Customized colour and size
Optional Glass fibre reinforcement
Available in ultra-soft pad to achieve over 50% deflection under low stress.

THERMAL GEL Thermal Gel - PPT-20
Product Features Typical Applications
Thermal Gel is a soft, single part, silicone putty thermal gap filler in which no cure is required. This gap filler is designed to be used in where large gap tolerances are present and low mechanical stress on delicate components are needed. It is ideal for filling variable gaps between multiple components and a common heat sink.
Thermal Gel has a composition which yields superior thermal performance and super compliancy. This material transfers little to no pressure between interfaces. Specialised rheology allows for easy flow under pressure
Soft and compliant transferring little to no pressure between interfaces
PPT-20-200, 300 & 350 offer high thermal conductivity with standard dielectric performance.
PPT-20-300C offer cost-effective solution and better dispensing speed which applied in non-strict dielectric requirements.

THERMAL GREASE Thermal Grease - PPT-30
Product Features Typical Applications
Thermal Grease is used in high performance CPU’s and GPU’s. With a high thermal conductivity of l.5-4W/mK, PPT-30 series thermal grease thoroughly wets out thermal surfaces to create very low thermal resistance.
Thermal grease eliminated the migration issues of silicone-based grease to create superior reliability. PPT-30 series is ideal for situations where automatic dispensing and screen-printing are required.
PPT-30 series is non-toxic and environmentally safe. PPT-30 series is available in 2kg(ll container), 8kg (1 gallon) and 20 kg (5 gallon) or custom package in syringes for automated applications.
PPT-30-300 & 400 offers a high thermal conductivity of 3.0-3, W/mK while achieving thin bonding line thickness of 0.03mm.
PPT-30-100 is coat effective product with l. W/mK thermal conductivity.
PPT-30-400SF offers silicone-free base, ideal for silicone sensitive application.

THERMAL PCM Thermal PCM - PPT-40
Product Features Typical Applications
Phase change material is designed to maximize heat sink performance and improve component reliability. Thermal Phase Change Material completely fills interfacial air gaps and voids. It also displaces entrapped air between power dissipating electronic components.
At room temperature, PPT-40-400 material is solid and easy to handle. This allows it to be consistently and cleanly applied as dry pad to a heat sink or component surface. Upon reaching its melting temperature of 52 °C, PPT-40-400 begins to soften and flow, filling the microscopic irregularities of the component it comes into contact with. The result is an interface with minimal bond-line thickness and thermal contact resistance.
PPT-40-400 can be supplied as sheets, rolls and custom die-cut configurations.
Low thermal resistance ( 0.015°C-in2/W@ 50 psi)

THERMAL ISOLATION Thermal Isolation Material - PPT-60
Product Features Typical Applications
THIM is a new thermal isolation material by adding aerogel into the ceramic base. You can achieve low through-plane thermal conductivity, even with high operational temperatures. Aerogel has a nano-structure which limits thermal transition, enabling the thermal conductivity to be as low as 0.025W/mK, which is 2 to 3 orders less than other solid material. Th e material also has good Inflaming and is UL 94V0.
