Embodiment 1

[0079] Example 1 - PP composition with talc

[0080] The composition is as follows:

[0081] 28.00 wt% commercial heterophasic polypropylene (PP Heco1, C 2 Content is 5.4wt%, MFR 18g / 10min, Lyondell Basell Industries (Lyondell Basell Industries));

[0082] 28.00 wt% commercial heterophasic polypropylene (PP Heco 2, C 2 The content is 10.0wt%, MFR70g / 10min, Lyondell Basell Industries);

[0083] 20.00 wt% of Steamic T1 C A talc purchased from IMERYS (hydrated magnesium silicate, d50 (Sedigraph 5100) = 2.0, layered index = 1.8));

[0084] 11.00wt% ethylene / 1-butene plastomer (Engage TM 7467, The Dow Chemical Company);

[0085] 6.00% by weight of commercially available high-density polyethylene (HDPE, MFR (190° C. / 2.16 kg)=14 g / 10 min, Lyondell Basell Industries);

[0086] 2.65% by weight of a commercially available polypropylene homopolymer (PP homo 1, MFR = 10 g / 10 min, LyondellBasell Industries);

[0087] 0.50wt% of β-cyclodextrin ( W7, Wacker Chemie);

[0088] A st...

Embodiment 2

[0089] Example 2 - PP composition with talc

[0090] Except that the concentration of commercial polypropylene homopolymer (MFR=10g / 10min) is 2.15wt%, and The composition of Example 2 was constructed with the same components and amounts as in Example 1 except that the concentration of β-cyclodextrin was 1.00 wt%.

Embodiment 3

[0091] Example 3 - PP composition with talc

[0092] Except the cyclodextrin used is from Wacker Chemie The composition of Example 3 was constructed with the same components and amounts as in Example 1 except for 7M methyl-β-cyclodextrin.

Abstract

A polyolefin composition comprises at least one polyolefin, up to 50.0% by weight of a filler, and from 0.05 to 2.5% by weight of at least one cyclodextrin.

Description

technical field [0001] The present disclosure relates to polyolefin compositions comprising cyclodextrins for the production of molded articles such as water pipes and articles for the automotive and packaging industries. Background technique [0002] Original Equipment Manufacturers (OEMs), especially in the automotive industry, have stringent odor specifications for all interior applications and heating and air conditioning units (HVAC). [0003] The most common method for determining odor is VDA 270, in which a sample of material is heated in a small closed flask and then subjected to an odor detection test by a qualified human population. Grading is done on a scale of 1 (no odor) to 6 (very odorous). Most OEMs set the odor limit at less than 3, but it is almost impossible to achieve this value with most commercially available polypropylene compounds. Due to the high requirements in automobiles for long-term thermal stability, UV resistance, scratch resistance, surface ...
