3M™ Thermally Conductive Silicone Interface Pad 5591

Product code: 5591
Manufacturer: 3M
Package size:
Shelf Life: 12 months

3M™ Thermally Conductive Silicone Interface Pad 5591 is designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. 3M™ Thermally Conductive Silicone Interface Pad 5591 consists of a highly conformable and slightly tacky silicone elastomer sheet filled with thermally conductive ceramic particles, which helps provides enhanced thermal conductivity and excellent electrical insulation performance.

FEATURES

Very good softness and conformability even to non-flat surfaces
Good thermal conductivity
Good electrical insulation properties
Compression relaxation properties help reduce pressure to electric components
Slight tack allows pre-assembly
Good wettability for improved and lower thermal resistance

APPLICATIONS

Integrated chip (IC) packaging heat conduction
Heat sink interface
Chip on film (COF) heat conduction
LED board thermal interface material (TIM)
HDTV integrated chip (IC)
General gap filling in electronic device

Automatic lubricator applying ROCOL high temperature chain oil to a roller chain

High Temperature Chain Lubrication Solutions – How to Choose the Right Chain Oil

https://prostech.vn/high-temperature-chain-lubrication-solutions/

High temperature chain lubrication keeps oven, dryer and conveyor chains running reliably at temperatures where ordinary oils smoke, evaporate and turn into carbon. As an authorized distributor of ROCOL (ITW) in Vietnam, PROSTECH helps maintenance teams choose the right chain lubricant by temperature, environment and food safety requirement – from standard conveyors to ovens at +550°C.
