Self-extinguishing Behaviour Thermal Resistance

Can vermiculite be used in polymer composite?

For the application of vermiculite in polymer composite, the key issue is to achieve an effective dispersion and exfoliation of the platelets into the polymer matrix to yield well-aligned and high-aspect ratio particles with mechanical reinforcement or a tortuous diffusion pathway to improve barrier properties .

Can vermiculites be modified with surfactants?

There are two notes regarding the modification of vermiculites that worth pointing out. Firstly, the modification of vermiculites with surfactants extends the interlayer space of the vermiculite and increases the interactions of vermiculite and polyvinylbutyral (PVB), leading to the increase of the elastic modulus of PVB.

How does expanded vermiculite affect a mortar?
