How do you use the Sylgard 184 silicone elastomer kit?
Thoroughly mix SYLGARD 184 silicone elastomer, base & curing agent, in a ratio of 10 parts base to 1 part curing agent, by weight. Agitate gently to reduce the amount of air introduced. Allow mixture to set 30 minutes before pouring.
What is sylgard used for?
Sylgard™ 184 can be used for many applications, a few of which are: encapsulation of amplifiers, coils, connectors, coils, equipment modules, circuit boards, transformers, solar cells, and ferrite cores.
What is the density of PDMS?
0.965 g/cm3
The density of PDMS was 0.965 g/cm3, which is similar to the mass density of the kidney, 1.066 g/cm3.
Is silicone A elastomer?
A part from Latex (the natural product), most elastomeric products fall into the category of “Synthetic Elastomer” the use of the word elastomer is used interchangeably with rubber nevertheless, Silicone is more correctly an “elastomer”.
What is PDMS elastomer?
Polydimethylsiloxane (PDMS) is a silicone elastomer most often used in microfluidic or lab-on-a-chip applications to form devices with defined microstructures. Many formulations of PDMS exist, with Sylgard 184 being the most commonly used in biological-based research.
What is the elastic modulus of PDMS?
PDMS elastic modulus range is between 0.57 MPa and 3.7 MPa, and varies linearly with the amount of crosslinker in the tested range. It is important that full contact is developed between the sample and the flat punch by pre-loading, and the use of the flat punch ensures constant contact area throughout the test.
What temperature does PDMS cure?
For microfluidic applications, PDMS is typically cured over a master in a plastic Petri dish at 80ºC for 2.5 hours. The curing temperature is limited by the maximum temperature a plastic Petri dish can withstand without warping.
How are silicone elastomers made?
The silicone polymer is mixed with reinforcing fillers and processing aids to form a stiff gum, which can then be crosslinked at elevated temperature using either peroxides or polyaddition curing. Once crosslinked the silicone becomes a solid, elastomeric material.
Is PDMS a dielectric?
PDMS is widely used in electronic applications as a polymer matrix due to its insulating properties, flexibility, thermal stability, and chemical resistance. These polymer nanocomposites develop unique dielectric properties by adding conductive fillers such as carbon black.
Can acetone dissolve PDMS?
Swelling of PDMS in organic solvents This general trend deviates in small but important ways, e.g. acetone and methylene chloride have indistinguishable solubility parameters but methylene chloride swells PDMS much more than does acetone.
Is PDMS soluble in water?
PDMS compounds such as amodimethicone, are effective conditioners when formulated to consist of small particles and be soluble in water or alcohol/act as surfactants (especially for damaged hair), and are even more conditioning to the hair than common dimethicone and/or dimethicone copolyols.
