“…Comparing to pure resin, the blending has slightly lower elongation (2.26 -5.07%), probably because of difficulties in obtained homogenous plastisol when blending two resin with different molecular weight. Some paper also shows similar negatives effect of blending inhomogeneitiesto the tensile strength and elongation (Mehdipour et al, 2017;Selvaraj et al, 2015). Therefore, there is should a compromise between the defect and mechanical properties that still suited the product requirements.The table 3 and figure 2 shows that the best compromise is sample D5A5 that gives none defect with tensile strength value 3.95/1.28 N/mm 2 (vertical/horizontal) and elongation 43.61/181.89 % (vertical/horizontal).…”

“…Blending processes allows the combination of the useful and desired properties from different polymers (Du et al, 2012). The mechanical properties of a blend depend on many factors including initial properties of blends material, composition, interfacial interaction and phase morphology (Mehdipour et al, 2017). In this paper, we focused on the variation ofblends constituent and composition.…”

“…At the opposite, larger k-value differences between the resin may result in difficulties at homogenizing the plastisol. Furthermore, incompatible polymer blends generally showed lower mechanical properties (Mehdipour et al, 2017). Therefore, in this works, the resin used in the blending process is from neighboring k-value (the biggest differences is 10 units) in order to adjust the mean k-value of the compound to processing equipments.The resulted mechanical test is shown in table 3 and figure 2.…”

“…From figure 2(a) and 2(b), the highest tensile strength (4.88 N/mm 2 ) and longest elongation (48.36 %) achieved by sample D10 (resin D 100 phr) for vertical test but gives many microporous defects. Pure resin D, without blending with other resin give better mechanical properties since there are difficulties in interaction between non-similar long chains in blended polymer system (Mehdipour et al, 2017). Comparing to pure resin, the blending has slightly lower elongation (2.26 -5.07%), probably because of difficulties in obtained homogenous plastisol when blending two resin with different molecular weight.…”

Artificial leather offer wide variety of application thus the demand is increased over time. The variation of the product needs different properties that can be achieved using resin with suitable k-value.This works reports the influence of the resin k-value on the mechanical properties of the artificial leather. The combination of various resin with different k-value (66, 68, 72, 74, and 76)is used and the tensile strength and elongation at break of the product were evaluated. The results show that blending the PVC resin with different k-value can be used to adjust the easier processing of the lower k-value and better mechanical properties of the higher k-value. Larger k-value differences between two resin make more difficulties of resin blending thus give more defect. For the blending of two resin, the tensile strength and elongation value would be between both of the resin initial properties. The final properties will be closer to the resin with a higher percentage in the resin blending.

Rigid polyvinylchloride (PVC) is widely used in various fields, but its low impact strength at low temperature limits its deep application in some cold regions. This work utilizes polycarbonate‐polydimethylsiloxane block copolymer (PC‐b‐PDMS) to toughen PVC. PDMS segment has extremely low glass transition temperature (−126°C) and PC segment has a good compatibility with PVC, which proved by the Fourier transform infrared and dynamic mechanical thermal results. For verifying toughening effect of PC‐b‐PDMS, the impact behavior at 23°C, 0°C and −30°C of PVC/PC‐b‐PDMS blends is investigated. The impact strength of modified PVC increases from 2.09 to 95.00 kJ·m−2 at 23°C, and the significant brittle‐ductile transition occurs at 10 phr PC‐b‐PDMS. At −30°C, 25 phr PC‐b‐PDMS makes brittle‐ductile transition appear and impact strength increased by 17 times. According to impact‐fractured morphology, PDMS acts as stress concentrator in PVC/PC‐b‐PDMS and produces a lot of cavities, crazes, and shear bands to consume impact energy, exhibiting good toughening effect. Overall, the PC‐b‐PDMS with excellent toughening effect is a promising alternative to traditional toughening agents, showing great promising application prospects in low‐temperature toughening of the rigid PVC products.
