The "iPitch" at the Stobart Stadium was criticised by former Warrington full-back Richie Mathers, who posted images of grazes to his body on Twitter.
He described the surface, on which his side won 32-14, as an "absolute joke".
But Widnes claim that Mathers' injuries are more likely the result of the icy conditions the match was played in.
The club's chief executive, Julie Gaskell, stated: "We had four games on the pitch this weekend and you have to bear in mind the extreme weather. On Friday night, it went down to minus seven.
We are happy for Widnes to continue using the iPitch
"The injuries are consistent with those on any surface in those temperatures. We noted there were similar injuries from the game at Salford on Saturday.
"Our players have been training on a similar surface for the last nine months and there have been no issues. I am sure any problems would have shown up.
"We have also had five-a-side football and boys and girls tag rugby on the pitch over the last four weeks and again we have had no reported injuries."
The Rugby Football League say their match commissioner had no concerns about the surface, which is the first artificial pitch ever to be used in the sport.
"We are happy for Widnes to continue using the iPitch," said RFL spokesman John Ledger.
"The indications are that it posed no more danger to players than on any other surface over the weekend. We believe the extreme weather may have been an issue."

Michael Salmon, 30, used his position as freelance producer of a show, "Cosy", at Cardiff's Millennium Centre, to obtain grants.
Some grants came from the Arts Council of Wales and Arts Unlimited, set up to fund projects with disabled performers.
Salmon, from Grangetown, Cardiff, admitted five counts of fraud.
The court heard that he used £9,000 to fund his own lifestyle, mainly on trips to London.
But most of the money he defrauded was lost by his own mismanagement of several theatrical projects.
One grant of £30,000 was obtained by falsifying a bank statement.
The deception took place between May 2015 and February 2016.
Jailing Salmon, Judge Paul Lewis QC said he had lied to theatrical directors who had gone to him for help in raising grants for their productions.
He said: "This was public money intended for good causes which never reached them.
"There was substantial financial mismanagement with money being transferred from one project to another when it shouldn't have been."

Northampton Town's League One 3-0 home win over Coventry City was disrupted several times by fans on Saturday.
Northamptonshire Police said six arrests were made when spectators from the away stand invaded the pitch and a further three when flares were let-off.
Coventry City said the disruption was "unacceptable". Northampton declined to comment. Those arrested were bailed.
Northampton Town said it would not comment until a decision was made by the Football Association or English Football League on an investigation.
"The repeated disruptions to yesterday's match at Northampton Town were unacceptable," a Coventry City spokesman said.
"Coventry City FC will support all subsequent investigations by the police and football authorities."
Match reports said the fans were protesting against the Coventry club's owners.
Supt Chris Hillery said: "During the fixture we were made aware that some of the spectators in the away South Stand had planned a mass pitch incursion at a designated time.
"As a result, match officials turned off the scoreboard time display and officers were placed in front of the West Stand and in the players' tunnel to prevent people intent on disorder entering these areas en masse."
There was no serious disorder, violence or injury, police said.
Widnes have rejected concerns raised about the safety of their artificial pitch following Friday night's Super League opener against Wakefield.
