“…46,47 When DOPO and Wo are simultaneously incorporated into the EP/CE blend in a certain ratio, the T 5% of 7DO/3Wo/EP/CE is slightly higher than that of sample EP/CE. Owing to the good thermal stability of Wo, 48 the char residue of sample 10Wo/EP/CE increases to 24.1% compared with that of the EP/CE blend at 700°C. The quantity of the residue of sample 7DO/3Wo/EP/CE is located in the range of the values of between sample 10DO/EP/CE and sample 10Wo/EP/CE.…”

Flame-retardant epoxy (EP) resin/cyanate ester (CE) composites were prepared with 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) and wollastonite (Wo). The combustion behavior of the flame-retardant EP/CE composites was investigated by limiting oxygen index (LOI), UL-94, and cone calorimeter tests. It is found that the EP/CE composite containing 7 wt% DOPO and 3 wt% Wo (sample 7DO/3Wo/EP/CE) exerts the best flame retardancy (LOI 35.5% and UL-94 V-0 rating). The peak heat release rate and total heat release of sample 7DO/3Wo/EP/CE increase slightly, while total smoke release decreases about 14% compared with the EP/CE composite containing 10 wt% DOPO (sample 10DO/EP/CE). Thermal studies indicate that the glass transition temperature and temperature at 5% mass loss of sample 7DO/3Wo/EP/CE are higher than that of sample 10DO/EP/CE. Moreover, the mechanical properties of EP/CE composites were investigated.

“…Another TPEs based on wollastonite‐reinforced styrene ethylene butylene styrene (SEBS)/PP/oil was prepared and characterized . The greatest increment of 41% in tensile strength was found with the addition of 2 phr of wollastonite but the further increase in wollastonite content did not show appreciable effect on tensile strength.…”

Wollastonite is a functional filler that has great potential to be used in thermoplastic composites, replacing more expensive reinforcement such as glass fiber. Wollastonite-reinforced polymer composite materials have attracted the attentions from research field and industries due to their biocompatibility and reinforcing ability in polymers. Due to the relatively high aspect ratio and hardness, wollastonite is able to improve the tensile and flexural strength of polymer composites. Many researches have been conducted to determine various properties of wollastonite reinforced polymer composites such as mechanical, flammability, thermal, and tribological properties in order to explore their potential in various applications. This review will focus on mechanical properties of wollastonite reinforced thermoplastic composites. Overall, it can be concluded that the properties of wollastonite-filled polymer composites are the function of filler content, adhesion interactions of wollastonite particles with polymer matrix, size and shape of wollastonite particles.Further research and development are needed to widen its application, and these include the use of nano-size wollastonite which can be produced synthetically as functional filler in thermoplastics.

“…1 In order to tailor its softness and processability, white oil is often added as extender oil. 2,3 In addition, several researchers have reported TPE blends of SEBS and polyolefin (PP 1,4,5 and high-density polyethylene (HDPE)) 6,7 that exhibited improved properties and enhanced performance through adjusting (PP and PE)/elastomer ratio. 5 However, the thermoplastic elastomer (TPE) based on SEBS mixed with polypropylene, polyethylene, and white oil makes it highly flammable and leads to intensive burning with smoke and soot production.…”

Aluminum hypophosphite combined with melamine cyanurate and poly(phenylene oxide) was applied to flame retard TPE-S system (blends of SEBS and polyolefin). TPE-S containing 16 wt% aluminum hypophosphite, 20 wt% melamine cyanurate, and 10 wt% poly(phenylene oxide) pass a V-0 rating in the UL-94 test and its limiting oxygen index value is 28.2%. Zinc borate and magnesium hydroxide were added to modify the AHP/MCA/PPO formulation. Thermogravimetric–Fourier transform infrared analysis tests showed that aluminum hypophosphite and melaminecyanurate acted in gaseous phase while aluminum hypophosphite and poly(phenylene oxide) helped to form char residue. TPE-S/AHP/MCA/PPO significantly decreased the heat release rate (reduction in peak heat release rate from 2001 to 494 kW m−2). Scanning electron microscopy/energy dispersive spectrometry results demonstrated that zinc borate and magnesium hydroxide promoted to retain more P and O elements in residue. Zinc borate and magnesium hydroxide in AHP/MCA/PPO formulation enhanced the char formation and reduced gas evolution of TPE-S, thus deteriorating the combination between gaseous phase and condensed phase.
